Objective: The utilization of iris-claw intraocular lens (IOL) in adult cases of capsular insufficiency has been investigated. However, the use of iris-claw IOL in the pediatric population is still under investigation. In this study, we evaluated the overall practice of iris-claw IOL implantation in pediatrics and compared the visual outcomes and postoperative complication rates between children and adults. Methods: Retrospectively, we examined the practice, indications, and outcomes of pediatric patients who underwent iris-claw “Artisan^®” intraocular lens implantation (IOL). All patients who underwent iris-claw IOL implantation for any causative indications were enrolled in the study. The outcome was compared by visual acuity and postoperative complications. Furthermore, the outcomes in pediatrics were compared to another adult group. Results: In this study, 41 eyes of 34 pediatric patients were included with a mean age of 11.1 years and a mean follow-up period of 24.5 months. Trauma is the most common indication for iris-claw IOL in pediatrics, followed by ectopia lentis and by congenital cataract. Iris-claw IOL was implanted anteriorly in 70.7% of pediatrics. Patients with retropupillary position achieved better visual outcome. Anterior iris-claw IOL had higher intraocular pressure readings and more decentration and disenclavation. In comparison with the adult group consisting of 130 eyes, pediatric iris-claw implantation was associated with more decentration and disenclavation, while adult practice was associated with more macular edema. Conclusions: Iris-claw IOL offers a relatively safe method for optical rehabilitation in pediatric patients where the capsular support is inadequate. Retropupillary implantation may achieve better visual outcome with less frequency of glaucoma and corneal endothelial loss. Full article

Background: The aim of this retrospective study was to compare the surgical and refractive outcomes using the Carlevale IOL (FIL SSF; SOLEKO) with those of the retropupillary-fixated Artisan IOL (Aphakia Model 205; OPHTEC), implanted through a 6 mm sclerocorneal tunnel incision in both groups. Methods: This study included 51 consecutive eyes (25 Carlevale and 26 Artisan IOLs). Due to complex preoperative conditions (e.g., dislocated polymethylmethacrylat IOL, luxated Cataracta rubra), all patients underwent lens explantation using a standardized 6 mm sclerocorneal tunnel incision and a 23 G or 25 G pars plana vitrectomy. Visual acuity (VA), spherical equivalent, refractive prediction error (PE), incision-suture time, and complication rates were recorded preoperatively and during the follow-up period. Results: The average follow-up period was 40.9 ± 5.7 days. VA improved by 0.28 ± 0.39 logMAR (p < 0.0001) in the Carlevale group and by 0.36 ± 0.47 logMAR (p < 0.0001) in the Artisan group. The improvement was comparable between both groups (p = 0.921). The deviation of the PE was −0.67 ± 0.56 in the Carlevale group and 0.34 ± 0.71 in the Artisan group (p < 0.0001). The mean incision-suture time was 42.5 ± 5.8 min in the Carlevale group and 28.2 ± 6.4 min in the Artisan group. Anterior chamber and vitreous hemorrhages were the most common complications, occurring in 12% in the Carlevale group and 17.2% in the Artisan group. Conclusions: The use of the Carlevale IOL, implanted using a sclerocorneal tunnel technique, presents a valid option for treating complex lens dislocations. The scleral fixation of the Carlevale IOL minimizes risks associated with iris fixation, such as chronic inflammation and pupil distortion, making it particularly suitable for patients with damaged irises.

Background/Objectives: This study aimed to evaluate the visual outcomes and prognosis after cataract surgery in patients with prior history of Verisyse phakic intraocular lens (pIOL) implantation. Methods: A retrospective cohort study involving 215 Verisyse pIOL implantations and 17 explantations was conducted. The Verisyse pIOL was disenclaved and removed through a superior scleral tunnel incision. Cataract extraction with phacoemulsification was then performed through a temporal clear corneal incision. Results: An occurrence rate of 7.9% of eyes with cataract formation was found. Both uncorrected (UDVA) and corrected visual acuity (CDVA) three months after cataract surgery were significantly improved (0.24 ± 0.30 vs. 0.73 ± 0.48; p < 0.001 and 0.10 ± 0.14 vs. 0.30 ± 0.31; p = 0.004, respectively). The UDVA was 20/20 or better in 41% of eyes and 20/40 or better in 65% of eyes. The CDVA was 20/20 or better in 53% of eyes and 20/40 or better in 88% of eyes. The safety and efficacy indices were 1.96 ± 1.68 and 1.60 ± 1.36, respectively. Conclusions: Various complications including cataracts may develop in these patients. Verisyse pIOLs have a lower incidence of cataract formation and are more likely to lead to age-related cataracts rather than the anterior subcapsular cataracts commonly seen in implantable collamer lens (ICL) patients. Patients with a prior history of Verisyse pIOL can expect to have a good visual prognosis after cataract extraction. Full article

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. Full article
