Unlike preceding methods, the Siepser Double Sliding Knot technique allows sutures to be tied within the eye without impairing delicate uveal tissue thus keeping a well-maintained anterior chamber during the process. Many old, new and emerging novel techniques for iris repair are utilized. Prior to the surgery, the surgeon puts dilating drops so as to enlarge the pupils. Randleman JB, Ahmed IIK. 2019;45(6):745-751. In this procedure the same technique for SFT (single pass four through) is utilized with a modification aimed to achieve a smaller (pinhole) pupillaery aperture (of approximately 1.3 mm in diameter) Dr. Stephen Wilmarth M.D. To provide structural support for lens implantation: 3. . Impaired night vision (in pinhole pupilloplasty).

Pupilloplasty Surgery in Albany NY - Cornea Care 1998 Dec;29(12):1001-9. 1241: Resident ACIOL and Pupilloplasty - Cataract Coach The power level and duration is variable, and we recommend using lower power levels (less than 20%) and short application time (1 second) and increased as necessary based on visible tissue reaction. This results in an improved self-esteem and quality of life for the patient. After the iris sutures are placed, we use iris cautery to refine the pupil centration and size. Step 1: Release adhesions to the iris Using a 27 gauge blunt cannula we need to instill anesthetic inside the eye and release any iris adhesions. The 26-guage needle is pulled along with the suture, then securely tied (D). Narang P, Agarwal A. Single-pass four-throw pupilloplasty knot mechanics. Thus, it is easy to control the pupil size and possible to adjust accordingly during surgery. A well-centered, round, and reasonably sized pupil is of critical importance to the cosmesis of the eye, which should not be ignored and recognized as an important outcome of pupil repairs. (b) Both suture ends are pulled. Several pupilloplasty techniques exist for iris defect closure and iris edge reapposition. Application of pinhole optics by performing PPP leads to significant improvement in image quality and helps to optimize visual potential in post-RK cases. your express consent. Osher described a modification of the Siepser slip-knot that allowed the knot to become locked, decreasing the chance of suture failure in 2005.

J Cataract Refract Surg. Endodiathermal pupilloplasty is a simple and effective strategy to recenter, enlarge, and shape the pupillary margin. This technique provides exquisite control to achieve a cosmetically pleasing pupil and iris repair, thereby improving the patient's quality of life. Endothermal pupilloplasty (EDP) does not remove or cut iris tissue, elicits minimal inflammation, has a short learning curve, and is titratable and controlled. Jordan E. TRAUMATIC IRIS RECONSTRUCTION USING PUPILLOPLASTY FOLLOWING THE SIEPSER DOUBLE SLIDING KNOT TECHNIQUE [Internet]. The pupil is reformed using these sutures to best approximate its location. Some minimal iris discoloration is expected, but this is often very subtle and visible only under the microscope (Figure 3). Intrinsic iris tension will then cause the linear cuts to spread apart. Procedures - Parker Cornea First, it is an effective and simple strategy to avoid causing additional trauma to the iris. Some minimal iris discoloration is expected, but this is often very subtle and visible only under the microscope (Figure 3). European Journal of Ophthalmology. CTR, pupilloplasty, traumatic cataract. Unlike experiences with corneal coagulative procedures, iris coagulation does not seem to regress. A method to perform pinhole pupilloplasty (PPP) in the setting of previous RK is presented. In cases of a small pupil, cautery can be applied circumferentially to enlarge the pupillary margin. These defects can result in various issues including loss of visual acuity, increased optical aberrations, photophobia, glare, and night vision disturbances. 1077: traumatic cataract & pupilloplasty - Cataract Coach 2019;35(3):207-208. Siepser SB. You may be trying to access this site from a secured browser on the server. To provide structural support for lens implantation: 2.1.33. Wolters Kluwer Health Current options include removing or cutting iris tissue using microscissors or the vitreous cutter, instrument stretching, or postoperative laser photocoagulation. 1979 Apr 1;5(2):150-3. Furthermore, a greater effect can be obtained with endodiathermy, which can also be adjusted with additional sutures to refine the iris and pupil appearance. Educational Objective Improve management of surgical complications Course Description Video based course, highlighting important aspects of papilloplasty and iris reconstruction. Endothermal pupilloplasty to optimize pupil centration, size - LWW when used in ACG , iris traction would be proportional to the degree of angle closure. It will include surgical planning guidelines, basic and advanced iris suturing . EDP could possibly avoid these complications, introducing minimal instrumentation into the anterior chamber, thereby reducing trauma, potential endothelial damage, and risk for iatrogenic damage during surgery. This can be accomplished by direct closure of iris defects and pupil irregularities with sutures or with an iris prosthesis in cases where there is insufficient iris tissue.1 Although challenging, we prefer to primarily repair the iris if sufficient iris tissue exists as this results in the most natural appearance of the eye. In these cases, an iris prosthesis is likely more appropriate.1. When you look at this post-op slit-lamp microscope photo, you may initially think that it looks less than ideal. The pupil is an aperture or an opening in the center of the iris of the eye. Cataracts signs, symptoms: How to know when it's time to get surgery Annals of Eye Science. Follow-up examinations were scheduled up to 3 months postoperative to assess the success of the procedure by comparing visual acuity and IOP at baseline and 3 months after the operations. Preoperatively, the third patient in the series has a pathologically large pupil in an aphakic-vitrectomized eye (A). This technique was especially useful in cases of multifocal intraocular lenses. [8], Although pupilloplasty is rarely performed solely for cosmesis, it can be considered, especially in large colobomas in a colored iris and it can provide functional and cosmetic repair.[9]. 2018;2:31-31. Stopa M, Rakowicz P. Sutureless iris repair: cauterization technique. The McCannel suture: a bimanual technique. 11. The most pleasing aspects of a pupil are its centration, shape, roundness, and symmetry. In this technique a running suture is passed around the pupillary margin to create a purse-string suture aiming for a smaller pupillary aperture size in selected cases with symptomatic abnormally dilated pupil (such as traumatic mydriasis or atonic pupil). The artisan IOL is inserted, and the lens is properly enclavated in the anterior chamber (F). Journal of Cataract & Refractive Surgery: December 2021 - Volume 47 - Issue 12 - p e80-e83. Frisina R, Parrozzani R, Tozzi L, Pilotto E, Midena E. Pupil cerclage technique for treatment of traumatic mydriasis.

Ocular Surgery News | Pupilloplasty is performed to alter or change the shape of a pupil that does not conform to normal pupillary dimensions, and there are several techniques surgeons can use. Indications for surgery can be divided into these five main categories: A. Symptomatic iris defects can be considered for surgical intervention, symptoms can range from glare, shadow images and diplopia. The re-creation of an optimally sized and centered pupil is often challenging because of missing iris, asymmetrical iris damage, or variable tension around the pupil. There are several advantages that EDP offers over current pupil reshaping techniques. Financial disclosure: None, Ophthalmologist, Dr. Sardjito General Hospital; Ophthalmology Department, Faculty of Medicine, Public Health, and Nursing, Universitas Gadjah Mada, Yogyakarta, Indonesia In most trauma cases, the defect can only be repaired using the suturing technique. The cosmetic result is particularly notable with this technique in the ability to produce an exquisitely round, centered, and symmetrical pupil in our experience. When cataract or intraocular lens surgery is performed in patients with traumatic pupil dilation and iridodialysis, the optic edges of the implanted lens are often exposed, regardless if the lens is within the bag or fixed by sutures, causing the patients to feel intolerable halo or inability to focus on objects after surgery. Thus, it is easy to control the pupil size and possible to adjust accordingly during surgery. Management of aniridia and iris defects: an update on iris prosthesis options. your express consent. Free. This activity is supported by an independent medical education grant from Genentech, a member of the Roche Group. 9. Pupilloplasty - EyeWiki January/February 2022 | Global Perspectives, Repairing surgically aphakic patients who have had a previous vitrectomy is complicated due to insufficient capsular support and/or major alterations in the anatomy of the anterior chamber, especially in the presence of iris defects.1,2, A significant cause of iris defects is pupil atonia, one of the most common complications of anterior segment surgery. Endodiathermy may be applied as many times as necessary to the peripupillary iris to achieve an ideal pupil shape and contour. Trauma, postoperative sequelae, elevated IOP, chronic uveitis, herpes simplex virus, herpes zoster virus, and proliferative disorders can all have a substantial impact on physiological pupillary dimensions, and as such, the iris must be thoroughly assessed for proper management of the defect.1,7, The primary consideration of our study was whether iris dysfunction may be repaired with a combination of pupilloplasty and iris-fixated IOL implantation. We recommend initially applying cautery to the midiris stroma instead of an area closer to the pupillary margin to avoid any exaggerated pupil enlarging effects. The iris may be stuck in the angle of the eye, on the cornea, or to the lens capsule. As there is no microcutting of the pupil margin as opposed to titratable contraction of peripupillary tissue with EDP, the pupil margin tends to retain its smoothness and avoids irregular edges. (e) Both suture ends pulled. The pupillary stretch is performed every 2-clock hours around the entire pupillary margin. Endothermal pupilloplasty (EDP) does not remove or cut iris tissue, elicits minimal inflammation, has a short learning curve, and is titratable and controlled.

Many of these symptoms can cause severe disability and significantly impact quality of life. Stopa and Rakowicz described a sutureless approach to the reapposition of iris tissue edges by using iris cautery instead of suturing to achieve a connection in cases of sectoral iris defects, traumatic mydriasis, and iridodialysis.2 Xiang et al. Ocular Surgery News | Manual small-incision cataract surgery is an established method to perform cataract removal and is often considered as an alternative and a standby procedure to . 1423: subluxated cataract & pupilloplasty - Cataract Coach Complex cataract surgery, iStent, Pupilloplasty. 2020 [cited 19 March 2020]. Refractive Surgery The specialists at Parker Cornea work to provide you with the best vision possible through a wide variety of refractive surgery options, including implantable collamer (contact) lenses, refractive lens exchange / clear lens extraction, and pinhole pupilloplasty. Cataract surgery - Mayo Clinic The iris cerclage suture for permanent mydriasis: a running suture technique. [Internet]. To the authors' knowledge, this is the first description of EDP. This results in an improved self-esteem and quality of life for the patient. EDP is a straight forward and minimally traumatic method to optimize pupilloplasty outcomes by improving pupil centration, size, and contour. [22]. The goal of this technique is to create and maintain an appropriate pupil size to alleviate symptoms while still permitting adequate light during scotopic conditions and allowing for an adequate posterior segment examination. The functional and cosmetic outcome of iris defect repair is often not ideal, resulting in intolerable glare, photophobia, visual distortion, and poor cosmesis. A vitrector or microscissors can cut and attempt to reshape the pupil; however, both consist of cutting or removing tissue and typically do not leave a smooth and circular pupillary margin. Wise J. Iris Sphincterotomy Iridotomy, and Synechiotomy by Linear Incision with the Argon Laser. In our study, there were no complications reported by any patient during surgery or in 3 months of routine monitoring. J Refract Surg. Complex cataract surgery, iStent, Pupilloplasty. Shannon Wong - YouTube Several pupilloplasty techniques exist for iris defect closure and iris edge reapposition. During cataract surgery, your eye surgeon will remove the cloudy crystalline lens from the eye and replace it with a clear . 1985;104:558-62. 1077: traumatic cataract & pupilloplasty. What are the advantages of RLE? It minimizes instrumentation and tissue manipulation in the anterior chamber to achieve excellent functional, visual, and cosmetic outcomes and can be readily accessible in most operating rooms.WHAT WAS KNOWN Unlike experiences with corneal coagulative procedures, iris coagulation does not seem to regress. Iris and pupillary abnormalities may occur from a variety of conditions, including trauma, congenital, proliferative, and iatrogenic causes. A 26-guage needle is introduced into the anterior chamber and passed through the iris tissue (C). Single-pass 4-throw pupilloplasty technique for angle-closure glaucoma.

Wolters Kluwer Health IC-301 The Art of Pupilloplasty and Iris Reconstruction Surgery: Tips and Tricks. The medical term for this common complication is known as posterior capsule opacification (PCO). Data is temporarily unavailable. Furthermore, when focal sutures are placed, the remainder of iris tissue is able to dilate. European Journal of Ophthalmology. 13. Then, make two incisions on either side in the limbus along the axis of the iris defect. After applying cautery, attention should be paid to ensure that iris tissue is free from the cautery tip before removing it from the anterior chamber. If IOP drops, the globe must be filled with balanced salt solution immediately. A 23-gauge endodiathermy straight blunt tip bipolar cautery (Dutch Ophthalmic Research Center). Radial keratotomy (RK) was the most commonly performed refractive surgery in 1980s that involved . A novel pupilloplasty in crescent-shaped suturing pattern for coloboma 1st ed. Preoperative documentation of contralateral pupil size is helpful as a reference. Our results support previous findings that the combination of pupilloplasty and iris-fixated IOL implantation under local anesthesia can be a quick and simple way to treat aphakic-vitrectomized eyes with insufficient capsular support and atonia. Pinhole Pupilloplasty for Higher Order Aberrations: Assessment of Ophthalmology. The pupil plays an important role in ocular function, vision, light transmission, and cosmesis. We recommend a bipolar as opposed to monopolar cautery for safety reasons and prefer more of a blunt tip rather than a sharp tip to avoid tearing or snagging tissue. [13] Using a case series approach, we describe the management of three aphakic vitrectomized patients (three eyes) who have a pathologically wide pupil (atonia) and insufficient capsular support. These can be categorized into surgical and non-surgical methods: Various techniques had been advocated for pupillary reconstruction, all shared a common goal; restoration of shape regularity and/or centration of the pupillary aperture aiming for a better quality of vision. Although the pupil is less likely to dynamically dilate and constrict with iris damage, with tissue loss, or after surgical repair, achieving a moderately sized pupil provides a good balance of visual, functional, and cosmetic symmetry with the fellow eye. IC-115 Dropfree Cataract Surgery: Take Control of Perioperative Care. This result was similar to a previous study in which uncorrected visual acuity rose significantly from 1.15 0.29 logMAR to 0.37 0.17 logMAR at 6 months after surgery (P < .05).3, In addition, IOP from admission date to 3 months after surgery showed normal results with a range of 16 mm Hg to 17 mm Hg for all patients. . 1423: subluxated cataract & pupilloplasty Uday Devgan MD March 30, 2022 guest surgeons, sutured IOL, trauma, zonulopathy Previous Next This patient sustained an ocular injury which resulted in subluxation of the crystalline lens, cataract formation, and chronic traumatic mydriasis. Intraocular lens surgery: selection, complications, and complex cases. Because of cosmetic concerns, surgeons should repair the iris to achieve improved functional and aesthetic outcomes.12 All three patients included in this study were satisfied with the surgery, given that their visual acuity improved significantly and their symptoms of glare and photophobia reduced remarkably. If the pupil aperture is too large or an iris gap remains after cautery, the pupil shape may be refined by returning to the suturing step and repeating the process to achieve a round and central pupil. However, there is suboptimal control with this technique and typically leads to irregular pupil margins, removal of tissue, and difficulty achieving optimal pupil centration and roundness. A similar nonsurgical technique for adjusting pupil location and size is argon laser pupilloplasty.4,5 This technique has been used postoperatively in eyes with a decentered multifocal intraocular lens to improve visual function.4 It may also be used in combination with argon laser peripheral iridoplasty to relieve pupil block.5 Although postoperative laser photocoagulation is an option, we do not find it as controlled as intraoperative adjustments. Functional or optical indications: 2. Tie the suture securely and repeat the procedure until the normal pupil size is achieved. 2017;29:184-188. Endodiathermal pupilloplasty: a technique to optimize pupil - LWW More sophisticated techniques are required to address pupil centration, contour, and aperture size to optimize outcomes of pupil reconstruction beyond just iris defect closure. .

Using a 26-gauge needle, introduce a polypropylene suture through the limbal incision, passing straight through the iris (1 mm from pupil) and exiting through the contralateral side of the iris. A long, curved transchamber needle on 10-0 polypropylene is passed in and out of the anterior chamber through limbal paracentesis openings while weaving the needle through the iris near the pupillary margin to form the cerclage. The pupil may contract or dilate depending on the amount of light entering the eye. Ye P, He F, Shi J, Liu J, Liang G, Wu J et al. CPT Code 66682 - Repair Procedures on the Iris, Ciliary Body - AAPC Iris defects and distorted pupils are commonly managed with iris suturing techniques that aim to close the defect and/or reform the physiological pupil. 2019;30(3):480-486. This is controlled by the level of energy applied, duration of application, and, most significantly, distance from the pupil margin. A vitrector or microscissors can cut and attempt to reshape the pupil; however, both consist of cutting or removing tissue and typically do not leave a smooth and circular pupillary margin. In addition, the self-consciousness around having a distorted pupil can impact the patient psychologically with loss of confidence and self-esteem. J Ophthalmol 2019;2019:17. Many of these symptoms can cause severe disability and significantly impact quality of life. Cataract Surgery: Modern History. Although the pupil is less likely to dynamically dilate and constrict with iris damage, with tissue loss, or after surgical repair, achieving a moderately sized pupil provides a good balance of visual, functional, and cosmetic symmetry with the fellow eye. J Cataract Refract Surg. Endothermal pupilloplasty (EDP) may be used to recenter or enlarge a small pupil, thereby avoiding additional trauma inflicted by a vitrector or microscissors that physically cuts the iris. I performed a laser pupilloplasty on those who did have visual disturbances, and none of these patients has experienced a worsening of symptoms. A full thickness stab incision is then created between the paracenteses through the peripheral cornea. A hook introduced through the stab incision is used to bring both ends of the suture out of the eye where it is then tied pulling the pupillary edges together to close the defect. Single-pass four-throw pupilloplasty for angle-closure glaucoma We chose the SFT technique because it provides some advantages over other techniques, including reduced surgical manipulation, fast surgical time, and dissemination of the pigment in previously compromised eyes.7,8 It also offers faster rehabilitation and reduced inflammation in postoperative settings.9 Recently, interest in the SFT technique has grown because it can significantly reduce photophobia and glare.10,11 All procedures were performed under local anesthesia (topical pantocaine and intracameral lidocaine 2%) under monitored care. Scalloped, irregular, and noncircular edges often result. 2010;30(1):131-9. We describe a new surgical approach to adjust a decentered pupil to achieve a more centered, round, and circular pupillary margin using bipolar microendodiathermy. The use of Healon in McCannel suturing procedures. . [7], Single pass four through pupilllplasty can be used to break PAS and angle apposition angle closure glaucoma whether primary, post trauma, plateau iris syndrome, Urrets-Zavalia syndrome, and in cases associated with long standing silicone oil in the anterior chamber. Retina. Furthermore, coagulation may induce some inflammation, but this can be well controlled with early postoperative topical steroids.

Hardjolukito Air Force Hospital, Yogyakarta Indonesia The 10-0 suture attached to the long arm of the needle is passed through the proximal iris tissue while the end-opening forceps grasp it. Financial disclosure: None, Medical Doctor, International SOS, Jakarta, Indonesia July 2021. This technique is regarded as the simplest form of surgical pupillplasty, with short learning curve. In our practice, we often perform EDP for cases of decentered and corectopic pupils, irregular pupil shape, or small pupillary aperture secondary to traumatic iridodialysis or iris coloboma. In addition, it is best to apply cautery away from the suture knot as it may result in a broken suture; however, this is uncommon. De Francesco, Ticiana MD; Ma, Jingyi BMSc; Ahmed, Iqbal Ike K.
