Background. To evaluate the outcome and complications of transscleral suture-fixated posterior chamber intraocular lens (PCIOL) implantation combined with Ahmed glaucoma valve (AGV) surgery in Asian eyes. Design. This was a retrospective study that included 22 eyes from 22 participants. The surgeries were performed at Singapore’s National University Hospital. Participants underwent an Ahmed tube surgery, together with transscleral suture-fixated posterior chamber intraocular lens. Main Outcome Measures. Complete success was defined as 6 ≤ intraocular pressure (IOP) ≤ 21 mmHg without medications at the last follow-up visit, with no reoperation required and no progression to no perception of light (NPL). Results. At the last follow-up, there was a significant reduction in mean IOP (22.4 ± 6.5 mmHg versus 13.9 ± 3.9 mmHg; p<0.001) and mean number of intraocular pressure-lowering medications (2.45 ± 1.30 versus 0.05 ± 0.21; p<0.001). There was no significant change in visual acuity [1.43 ± 1.21 (LogMAR) versus 1.09 ± 1.31 (p=0.204)]. Sixteen eyes (72.7%) achieved complete success. The 3 commonest complications were bullous keratopathy, choroidal detachment, and displacement of intraocular lens. Conclusion and Relevance. This technique showed good success for intraocular pressure control and vision preservation. Postoperative complications were relatively common although most were self-limiting. Patients at increased risk of trabeculectomy failure may be suitable for this procedure.

Purpose: We report the longest follow-up to our knowledge of stable scleral fixation of a posterior chamber intraocular lens (PC IOL) with 10-0 polypropylene sutures. Methods: A retrospective review is presented of a case with more than 30 years’ follow-up after performing sutured scleral fixation with 10-0 polypropylene suture using 2 sutures tied together under a scleral flap. One suture was a cow-hitch looped around the haptic, and the other suture was passed through the sclera to create the scleral fixation. Results: The scleral fixation with 10-0 polypropylene suture knots for both haptics of the PC IOL allowed central optic positioning with excellent vision for more than 30 years without suture breakage. Conclusions: Polypropylene sutures for scleral fixation of PC IOLs remained stable for more than 30 years with central positioning of the PC IOL, without exposure of the fixation suture knots through the conjunctiva, and without suture breakage.

The aim of this article is to report the results of an innovative technique for a scleral fixation of a posterior chamber intraocular lens using our new modified technique. We retrospectively reviewed the medical records of 15 eyes of 15 patients who underwent sutureless intrascleral intraocular lens fixation using our modified technique. We used a 23-gauge knife to perform sclerotomy and create two parallel scleral pockets for the haptics. The mean follow-up period was 3 years (3 ± 1). No complications were detected during the follow-up period. The creation of two parallel scleral pockets, parallel to the limbus, greatly simplifies the introduction of intraocular lens haptics.

Purpose To evaluate the efficacy and safety of aniridia posterior chamber intraocular lens (PCIOL) in traumatic aniridia and aphakia in vitrectomized eyes. Methods Four aphakic patients with traumatic aniridia and previous pars plana vitrectomy (PPV) due to posterior segment trauma enrolled in the study, and had secondary implantation of an aniridia PCIOL. Two patients were men and two women with mean age of 39.25 years. Complete ophthalmic examinations, including preoperative and postoperative visual acuity in dark and light, glare disability, visual function (using VF-9 questions modified from VF-14), stereopsis, and contrast sensitivity in 3, 6, 12, and 18 cycle per degree frequencies, were done for all patients. Postoperative intraocular pressure (IOP), IOL centration, and intraocular inflammation were monitored. Mean follow-up was 12.25 months (range 7 to 15 months). Results Visual acuity improved in all four patients, especially in the light. Glare was subjectively reduced in all of them. Stereopsis was measurable in three of them postoperatively. Contrast sensitivity improved in all patients, especially in brightness and lower frequencies. All four eyes had improved VF-9. All eyes achieved the desired anatomic results. Two cases developed elevated IOP early after surgery. In one eye, IOP elevation was transient and controlled with antiglaucoma medication, but the other eye, which had secondary glaucoma from previous trauma, required cyclophotocoagulation for the IOP to be controlled. No patient developed chronic uveitis or redetachment. Conclusions The aniridia PCIOL can overcome aphakia, reduce glare, and increase visual function, contrast sensitivity, and stereopsis in vitrectomized eyes with traumatic aniridia. Although this kind of IOL appears safe, some disadvantages are secondary glaucoma and reduced visibility of peripheral fundus, and caution should be used in its implantation until more patients with longer follow-up are studied.
