“…Compared with AC IOL, retro-iris implantation is the main advantage of scleral-fixated PC IOL. Therefore, damage of the endothelial cells and the angle structures can be avoided [ 1 , 17 , 18 ].…”

Purpose. To evaluate the short-term safety and efficacy of a novel approach of utilizing the 9-0 looped polypropylene suture with double knots buried into the scleral groove and the scleral tunnel to minimize the risk of the suture erosion and suture knot exposure. Design. Clinical-based retrospective study. Methods. Records of consecutive patients who had anterior vitrectomy and scleral-fixated posterior chamber intraocular lens (IOL) implantation between July 2018 and April 2020 with a minimum follow-up of 3 months were reviewed. Results. This study enrolled a total of 21 eyes from 20 patients (15 male). These patients had a mean age of 58.52 ± 8.55 years and were followed for an average of 1.08 ± 0.58 years postoperatively. Best-corrected visual acuity (BCVA) improved from a preoperative mean of 0.43 ± 0.41 logMAR to a significantly higher mean 3-month postoperative value of 0.09 ± 0.21 logMAR (Z = -3.35, p < 0.01 ). There were no statistical differences between the preoperative and postoperative corneal endothelial cell density ( p = 0.71 ). The postoperative complications included transient increased intraocular pressure in 5 eyes (24%). No other complications were detected during the follow-up. Conclusions. The modified technique proposed is a safe, effective, and reliable approach resulting in good visual outcomes. Our procedure might have the potential benefit to avoid suture-related complications in scleral-fixated IOL implantation. Trial registration. Retrospective case series study, not applicable.

“…In addition, Mora et al compared the functional and clinical outcomes of the iris-claw IOL placed on the anterior and posterior surfaces of the iris. They showed that fixing the iris-claw IOL on the anterior or posterior chamber is equally effective and safe for aphakic eyes with inadequate capsular support [ 30 ]. Other reports showed no changes in cECC after iris-fixed lens implantation when compared with sulcus-fixated lens implantation [ 8 ].…”

An iris-claw intraocular lens (IOL) has been widely used as a secondary implant in aphakic patients. The study presents the results of implanting the anterior chamber iris-claw Artisan IOL in cases of where an appropriate posterior capsular support is lacking. The study included 132 patients subjected to primary IOL implantation during complicated cataract surgery with damage to the posterior capsule (I), secondary implantation in aphakia (II), secondary implantation during penetrating keratoplasty (III), and secondary implantation during pars plana vitrectomy with luxated IOL extraction (IV). We analyzed the records of best-corrected visual acuity (BCVA), spherical equivalent (SE), intraocular pressure (IOP), and corneal endothelial cell count (cECC), taken before and 1, 2, 3, and 4 years after the surgery. BCVA depended on the time after IOL implantation and the primary indication. Four years post-surgery, the SE values were the lowest in group III. IOP was the same in all groups both before and after the surgery, but 4 years after the surgery IOP values in group IV were higher than in group III. The cECC decreased every year after the surgery in all groups, but four years after the IOL implantation, the lowest cECC values were observed in group IV. At the same time, all groups of patients showed improved BCVA, stable refraction, and a low percentage of postoperative complications.

“…This phenomenon may result from large posterior capsular contact of IOL and constant tension of zonular fibers brought by haptics, which together lead to good IOL centering with less dislocation [28, 29]. Several special IOLs including iris-claw IOL, iris fixation posterior chamber-IOL (PC-IOL) and IOL with stabilizing haptics should be recommended to enhance the stability [30, 31]. Some surgical improvements like suspensory IOL implantation and IOL clamping at capsulorhexis are also helpful for visual rehabilitation [32].…”

Background Anterior megalophthalmos is a rare congenital disease which mainly features enlargement of the anterior segment. Cataract surgeries in anterior megalophthalmos can be challenging due to the anatomical anomalies while the studies upon the surgical design have been less integrated. Case presentation A 37-year-old woman presented with progressively blurred vision in the right eye after a transient fever 10 months ago. Her ocular history included hypermetropia with a spherical equivalent of + 4.00 OU. The review of systems showed bilateral varus deformity of distal interphalangeal joints on the little fingers. The patient denied family history of hereditary ocular diseases and her sister was born with uterus didelphys. On initial examinations, the corrected distance visual acuity was hand motion OD and 20/33 OS. Her intraocular pressure was 15 mmHg OD and 16 mmHg OS. Horizontal corneal diameter was 14 mm OD and 13.88 mm OS and axial length was 24.87 mm OD and 25 mm OS. Anterior segment photography showed bilateral iridal atrophy with deficiency in pupillary dilation and white cortically mature cataract in the right eye. Inspection by anterior segment optical coherence tomography indicated bilateral augmented anterior chambers with backward iridal concave on horizontal orientation. Ultrasound biomicroscopy showed partially peripheral anterior synechiae and pectinate ligaments at chamber angle in both eyes and opacified lens with the apparently elongated suspensory ligaments in the right eye. A deliberately selected 1-piece foldable intraocular lens (IOL) with frame haptics was implanted after phacoemulsification for good IOL stability. During the follow-up, the visual rehabilitation appeared relatively good and a lower degree of IOL dislocation comparing with existing reports was verified by OPD-Scan III aberrometry. Conclusions We presented the challenges and the original findings from a case of congenital anterior megalophthalmos with white cataract who underwent phacoemulsification and IOL implantation. This is the first report describing the comparison of the different IOL power calculation formulas in anterior megalophthalmos. Compared to the SRK/T and the Holladay II formulas, the Haigis formula could be a more accurate choice for the IOL calculation in anterior megalophthalmos according to our case. Moreover, the deliberate selection of IOLs is essential for IOL stability in these patients.
