Alternate iris bypass technique of iridodialysis repair.

ABSTRACT: We describe a novel technique "alternate iris bypass technique" of iridodialysis repair in four patients experiencing traumatic iridodialysis along with cataract. In these cases, we have combined iridodialysis repair with phacoemulsification and intraocular lens implantation. The main advantage of this technique is that edges of the iridodialysis can be visible till the end of the repair by bypassing the iris tissue in alternate bites which helps in minimizing the corectopia of the pupil and localized iris clumping.

Modified sewing machine technique for iridodialysis repair, intraocular lens relocation, iris coloboma repair, Cionni ring fixation, and scleral-fixated intraocular lens.

Project description:The purpose of this study is to report the modification of sewing machine technique for iris dialysis repair (MSMT) and its usefulness in managing other conditions such as intraocular lens (IOL) subluxation, iris coloboma, Cionni ring for zonular dialysis, and for scleral-fixated IOL. MSMT was based on sewing machine principle using a prethreaded 26G/30G needle with prolene suture for minimally invasive iris dialysis repair in a closed chamber manner. So far, eight patients (trauma - 3, surgical complication - 5) underwent this procedure. This technique is further modified to extend its use for IOL relocation - 2, iris coloboma repair - 3, and Cionni ring fixation for zonular dialysis - 2, SFIOL - 5 patients. All 20 patients had good visual recovery and cosmetic outcome with minimal morbidity. To conclude, MSMT offers cost -effective, minimally invasive, easy to learn procedure with a potential to tackle several problems related with cataract surgery and iris defects, which even an average cataract surgeon can learn to perform when required. Further comparative studies with conventional techniques with large sample size are required to standardize this procedure.

A novel technique for closed-chamber iridodialysis repair.

Project description:PurposeWe introduce a novel technique for closed chamber iridodialysis repair.Materials and methodsWe use a 2.8-mm paracentesis knife to penetrate into the anterior chamber and create interrupted incisions in the sclera. The wounds are 1.5 mm distant from the limbus, at consistent 2.8-mm intervals along the dialysis area. After injecting viscocohesive ophthalmic viscosurgical device through a side port to relieve the synechia and to push the iris toward the incisions, the iris is then grasped by Kelman forceps through the sclera, dragged carefully, and incarcerated. After adjusting the tension of the iris according to the pupil shape, the sclera and the incarcerated iris tissue were sutured together with 10-0 nylon.ResultsThe technique was effective in six patients with traumatic iridodialysis.ConclusionOur surgical technique repairs the iris, restores the shape of pupil, as well as avoids creating a large incision in the limbus in patients suffering from iridodialysis.

Reversed scleral tunnel technique for repair of iridodialysis after blunt force trauma: a retrospective clinical study.

Project description:BackgroundTo investigate the efficacy and safety of reversed scleral tunnel technique for repairing iridodialysis after blunt force trauma.MethodsA total of 51 eyes of 51 patients with iridodialysis undergoing surgery were included in this study. Patients were divided into 2 groups: group A (the reversed scleral tunnel technique) and group B (the control group). Before the procedure and at 1, 3, and 6 months afterward, data on the patients' age, gender, treatments, diagnosis, mechanism of injury, best-corrected visual acuity (BCVA), intraocular pressure (IOP), degree of iridodialysis, lens status, concomitant ocular damage, number of sutures, complications, and follow-up time were collected and compared between the 2 groups.ResultsIridodialysis was repaired and the pupil shape was restored to nearly round in all eyes. Standard phacoemulsification or lens removal was performed in all eyes. A final BCVA ≥20/60 was achieved in 13 eyes (48.1%) in Group A and 13 eyes (54.2%) in Group B. The IOP remained stable during the follow-up period in all eyes except 2 eyes (7.4%) in Group A and 3 eyes (12.5%) in Group B with angle recession. There were no statistically significant differences in BCVA and IOP between group A and group B. Intraoperatively, A significantly lower percentage of extensive subconjunctival hemorrhage occurred in Group A compared to Group B (1 eye versus 24 eyes, χ2 = 47.1, P = 0.00). Hyphema was observed in 2 eyes (7.4%) in Group A and 1 eye (4.2%) in Group B. Postoperatively, two eyes (7.4%) in Group A and 2 eyes (8.3%) in Group B developed retinal detachment. No other complications were noted during the follow-up period.ConclusionsThe reversed scleral tunnel technique is a safe and effective approach for repairing iridodialysis after blunt force trauma with few complications, favorable cosmetic and visual outcomes.

A novel transconjunctival, intrascleral, ab-externo, knotless, and double-flanged technique with 6-0 Prolene for iridodialysis repair.

Project description:Small traumatic iridodialysis (ID) may be asymptomatic, but large ones usually cause polycoria and corectopia, leading to symptoms like diplopia, glare, and photophobia. The management of ID, including medical and surgical methods, depends upon the patient's symptoms. Mild glare and diplopia can be treated either with atropine, antiglaucoma medications, tinted spectacles, colored contact lens, or corneal tattooing, but extensive IDs require surgical options. The surgical techniques are challenging due to the iris texture and the damage encountered during the primary surgery, the narrow anatomical workspace for repair, and the associated surgical complications. Numerous techniques have been described by several authors in the literature; each has its advantages and disadvantages. All the procedures described previously involve conjunctival peritomy, scleral incisions, and suture knots and are time consuming. Here, we report a novel transconjunctival, intrascleral, knotless, and ab-externo, double-flanged technique for repair of large ID with a 1-year follow-up.

Single suture customized loop for large iridodialysis repair.

Project description:Managing large iridodialysis that may occur during phacoemulsification is challenging. I describe how a procedure to reposit a prolapsed iris while the anterior chamber is markedly inflated by a current of infusion fluid may inadvertently lead to large iridodialysis, and discuss how to avoid such a complication. I describe a fast and efficient technique for managing large iridodialysis both immediately, once it occurs, or as a secondary maneuver. My technique involved fixing the iris periphery back to its root at the anterior chamber angle using 10-0 polypropylene suture with two straight needles introduced directly through the cornea at distant points, and an insulin syringe as a guide track to a point 1.5 mm from the limbus at the base of a triangular scleral flap that was designed to be centered on the area of iridodialysis. I confirmed the simplicity, efficacy, and safety of my technique through a 1-year follow-up period.

Spatula scaffold: An iris-sparing technique for lensectomy.

Project description:Lensectomy with vitrectomy is often performed for crystalline lenticular subluxation. We report a new technique and a practical approach that involves the placement of a spatula beneath the iris tissue that facilitates retroiridial removal of subluxated lens and acts as a scaffold by protecting the iris tissue from being accidentally trapped into the vitrectomy cutter port. Our technique facilitates management of the lens and vitreous without any trauma to the iris and secondarily obviates the need to perform an iris repair procedure that may arise due to iatrogenic reasons.

Stacked implantation of two prosthetic iris devices for patients with iris defects: A modified surgical technique.

Project description:PurposeIris pigment deficiency in patients with oculocutaneous albinism (OCA) often causes debilitating photophobia, which is routinely managed by sequential intracapsular insertion of two aniridia rings. A common concern of this technique is the risk of segment interdigitation, which can lead to intraoperative complications.ObservationsIn this report, we describe a modified technique through which both rings were stacked together and inserted simultaneously in a 62-year-old male patient with oculocutaneous albinism and a mild cataract. The patient underwent bilateral phacoemulsification followed by implantation of two Morcher 50E aniridia rings simultaneously, prior to IOL implantation behind the implants within the capsular bag. Post-operatively, the patient's photophobia improved dramatically, and there were no post-operative complications.Conclusions and importanceSimultaneous insertion of two stacked aniridia rings prior to IOL implantation was a safe and successful alternative surgical method for the management of photophobia in patients with oculocutaneous albinism and cataracts.

Supermicrosurgical Suture-Stent Technique for A Lymphaticovenular Bypass.

Project description:Lymphaticovenular anastomosis (LVA) is a challenging procedure and requires a sophisticated supermicrosurgical technique. The aim of this study was to evaluate and establish a discrete supermicrosurgical anastomosis method using the "suture-stent technique". Forty-eight LVA sites of twenty patients with lower extremity lymphedema who had undergone LVA between July 2020 and January 2021 were included in this study. LVA was performed with the conventional technique or with the suture-stent technique. The patency of the anastomoses was evaluated using an infrared camera system intraoperatively. The success rate on the first try and the final success rate for each group were compared. After full application of the exclusion criteria, 35 LVAs of 16 patients including 20 limbs were included in the analysis. The ratio of good patency findings after anastomosis in the suture-stent technique group was 100%. The incidences of leakage or occlusion on the first try were statistically greater in the conventional technique group (29.4%) than in the suture-stent technique group (0%) (p = 0.0191). All anastomoses achieved good patency in the final results. With its minimal risk of catching the back wall during the anastomosis, the suture-stent technique can be considered an optimal anastomosis option for LVA.
