BACKGROUND Visual rehabilitation of aphakic patients include spectacle correction, contact lenses, and primary or secondary intra ocular lens (IOL) implantation. Spectacles are rarely used nowadays because of limited visual field, aniseikonia and peripheral refractive errors. Contact lenses are other options for correcting aphakia but can cause a lot of corneal complications. Options for correction of aphakic patients with lack of adequate capsular support include anterior chamber IOL (ACIOL), scleral fixated IOL (SFIOL), and iris fixated IOL. Implantation of a retropupillary IC-IOL provides the benefits of a PCIOL, and the duration of the surgery is also less. The retropupillary IC-IOL because of its position lowers the risk of endothelial decompensation is a better option. We wanted to evaluate the functional outcomes of retropupillary iris claw lens implantation. METHODS Secondary implantation of IC-IOL was done in 50 surgical aphakic eyes as a result of intraoperative posterior capsular rent with zonular dialysis (N = 43, 86 %) & large (> 7 clock hours) zonular dehiscence (N = 7, 14 %). Follow up was done on 1 st day, 7th day, 1 month, 3 months and 6 months. RESULTS 22 males and 28 females in the age group 40 - 78 years were operated. 78 % eyes (N = 39) had vision better than 6 / 12 while only 10 % eyes (N = 5) had < 6 / 60 vision and the remainder 12 % (N = 6) had vision between 6 / 18 & 6 / 36. Complications like acute postoperative iritis (N = 18, 36 %) pupillary distortion (N = 15, 30 %), pigment clumping (N = 10, 24 %), iris chaffing (N = 9, 21 %), secondary glaucoma (N = 5, 12 %) and IOL decentration (N = 3, 7 %) were seen. The mean difference in central endothelial counts before surgery and 6 months after surgery was 109 cell / mm2 (5.92 %). CONCLUSIONS Iris claw lens gives the dual benefit of good visual acuity and less complication rate in aphakic patients with lack of adequate capsular support.

Visual rehabilitation in aphakia has been a challenge with a wide variety of surgical options available for ophthalmologist. We report the visual outcome with retropupillary iris claw lens secondary to intra operative complications and secondary implantation in aphakia. An interventional study on 4 eyes of 4 patients was conducted. Preoperative visual acuity, slit lamp examination and fundus examination were carried out. Anterior vitrectomy and retropupillary fixation of iris claw lens were done. The primary outcome measure was best-corrected visual acuity and secondary postoperative complication was recorded at various intervals. All patients had visual acuity of ≥6/18 postoperatively. Sutureless retropupillary iris claw intraocular lens implantation is a good alternative of scleral-fixated intraocular lenses in aphakic patients.

In this study, the technique and results of iris-claw intraocular lens (IOL) implantation with corneal incision and single paracentesis were presented. Eighteen eyes of 18 patients who underwent iris-claw implantation surgery with a single paracentesis were included in this prospective study. Iris-claw lens was grasped by its forceps and placed into the anterior chamber through superior corneal opening. While IOL was held by forceps, a blunt enclavation spatula was introduced through inferior paracentesis. Then the spatula was directed toward underneath of iris through pupil and toward sides where iris was entrapped into the claw by gentle push of iris through the slotted center of the lens haptics. Mean age of patients was 54.28±25.21 years (7-76 years). Mean anterior chamber depth was 4.07±0.32 mm and mean keratometric power was 43.01±2.73 D. Preoperative BCVA was 20/63 or better in 8 (44.4%) patients. At the first postoperative month BCVA was 20/63 or better in 14 (77.8%) patients. Preoperative mean spherical refraction was +11.05±2.62 D, preoperative astigmatism was 2.15±0.85. Postoperative mean spherical refraction was - 0.58±0.25 D and mean astigmatism was - 1.92±0.67 D. The most frequent postoperative complication was mild corneal edema seen in three patients that resolved completely during the first week with medical treatment. Irisclaw IOL implantation can be performed easily with corneal incision and single paracentesis. Single paracentesis does not increase surgical time or cause inconvenience during the procedure.

Purpose. To describe and explore an alternative approach for sulcus intraocular lens (IOL) implantation in the absence of capsular support.Methods. The commonly available one-piece poly(methyl methacrylate) (PMMA) lens is stabilized in the sulcus by two intraocular horizontal strings of 10/0 polypropylene suture passed through the lens dialing holes in opposite directions to achieve a mechanical balance. The horizontal strings of 10/0 polypropylene work as a rail track for the IOL optics, allowing some side to side lens adjustment even following wound closure. The stability of the IOL was tested in vitro. Six aphakic patients underwent in-sulcus IOL secondary implantation using the balanced two-string technique. Patients were followed up for a minimum of six months. Best spectacle corrected vision was assessed. Lens centration and lens tilt were measured by anterior segment optical coherence tomography (AS-OCT).Results. All patients had successful lens insertion. Best spectacle corrected visual acuity (BSCVA) improved in all patients. Lens decentration ranged between 0.21 mm and 0.9 mm (average 0.53 mm). Lens tilt ranged between 1.2° and 2.8° (average 2.17°).Conclusion. The mechanically balanced two-string technique is an alternative option for sulcus IOL implantation in absence of capsular support, allowing lens centration adjustment with no additional risks.

Background. The management of patients with aphakia and/or lack of capsular support remains debated. The sutureless posterior chamber IOL (PCIOL) fixation is a very useful surgical option. The purpose of the study was to compare the early outcomes as well as post-operative best corrected visual acuity, refractive errors and complications of two different techniques of sutureless PCIOL secondary implantation. Methods. Patients who underwent secondary implantation from December 2019 to January 2021 in the Department of Ophthalmology of Creteil Hospital, and in the Granville Ophthalmology Center, were retrospectively included. Eyes implanted with the iris claw lens (Artisan Aphakia IOL model 205, Ophtec BV, Groningen, The Netherlands) were included in group 1, and eyes implanted with a newly developed sutureless trans-scleral plugs fixated lens (STSPFL, Carlevale lens, Soleko, Pontecorvo, Italy) were included in group 2. Results. Twenty-two eyes of 22 patients were enrolled in group 1, and twenty eyes of 20 patients in group 2. No difference was found in visual acuity between two groups (0.35 +/− 0.29 logmar for group 1 and 0.23 +/− 0.51 logmar for group 2) (p = 0.15) at mean post-operative follow up (6.19 +/− 3.44 months for group 1 and 6.42 +/− 3.96 months for group 2) (p = 0.13). Both the mean refractive error (MRE) and induced astigmatism (IA) were greater in group 1 compared to group 2, respectively: the MRE was 0.99 +/− 0.57 vs. 0.46 +/− 0.36 (p < 0.01), and IA was 1.72 +/− 0.96 vs. 0.72 +/− 0.52 (p < 0.01). Conclusions. No significant differences in terms of the recovery of visual acuity were found between the two groups. Group 2 (STPFL) gives better results in our sample due to less post-operative induced astigmatism and less refractive error.

Keratoconus and other ectatic disorders can be an unexpected finding in patients seeking refractive surgery. In this group of patients, refractive laser corneal procedures are in many cases contraindicated as they may worsen the disease. Implantation of toric phakic iris claw lenses is a safe and effective treatment in patients with stable keratoconus. Good results in terms of visual acuity, post-operative residual refractive error and patient satisfaction can be achieved.
