Objective. To evaluate and compare the impact of two sharp-edge optic foldable intraocular lenses (IOLs) of similar design made from different material (hydrophilic acrylic or hydrophobic acrylic) on visual function, anterior and posterior capsule opacification at one-year follow-up after cataract phacoemulsification. Material and methods. Seventy-two eyes of 72 patients scheduled for cataract surgery were included in a prospective clinical study. Two foldable sharp-edge optic posterior chamber acrylic IOLs of similar design were used. Thirty-nine eyes of 39 patients received a single-piece hydrophilic acrylic (PC 511, Ophtec) IOL and 33 eyes of 33 patients – single-piece hydrophobic acrylic (AcrySof, SA60AT, Alcon) IOL. Visual acuity, anterior capsule opacification (ACO), capsulorrhexis/optic overlapping, and posterior capsule opacification (PCO) were evaluated. The intensity of ACO was assessed subjectively. PCO values in the entire IOL optic area and in the central 3-mm optic zone were assessed using a photographic image analysis system (EPCO 2000). The patients were examined at one year postoperatively. Results. There were no significant differences in best-corrected visual acuity and capsulorrhexis/optic overlapping between IOL types at 1-year follow-up after surgery. In the single-piece hydrophilic acrylic IOL group, the grade of ACO density was significantly higher in capsulorrhexis rim area (1.56±0.71 and 1.00±0.75) and in the capsule/optic area (1.62±0.67 and 1.00±0.75) (P<0.05). PCO values of the entire IOL optic area (0.12±0.13 and 0.024±0.02) as well as in the central 3-mm optic zone (0.06±0.11 and 0.001±0.003) was significantly higher in the single-piece hydrophilic acrylic IOL group one year postoperatively (P<0.05). In 33.3% of cases of the single-piece hydrophilic acrylic IOL group, contraction of haptics to IOL optics was present one year postoperatively, which was not present in any case of the single-piece hydrophobic acrylic IOL group. Conclusions. One-year follow-up after cataract surgery has shown a significant difference in ACO and PCO development comparing single-piece hydrophilic acrylic and single-piece hydrophobic acrylic intraocular lenses. The effect of hydrophobic acrylic foldable lenses on preventing anterior and posterior capsule opacification is mainly a result of the acrylic hydrophobic biomaterial.

Purpose To evaluate performance of different intraocular lenses (IOLs) after cataract surgery in children aged less than 2 years with regards to rates of visual axis opacification (VAO). Methods This was a retrospective chart review of children <2 years of age undergoing cataract surgery with primary posterior capsulotomy, anterior vitrectomy, and IOL over a period of 5 years with minimum follow-up of 1 year at a tertiary care institute. Children with microphthalmos, persistent fetal vasculature, traumatic cataract, aphakia, secondary IOLs, or any other coexisting ocular disease were excluded. Results A total of 257 eyes of 159 children were included in the study. The mean age at the time of surgery was 11.63 ± 7.916 months (range 6-23 months). A total of 29 eyes of 16 children underwent phacoaspiration with implantation of SA60 AT (AcrySof, Alcon, Fort Worth, TX); 75 eyes of 45 children received Hoya IOL (Hoya-PS AF-1 Series, Model PC-60AD, Hoya, Japan), 70 eyes of 46 patients received Sensar (Abbott Medical Optics Inc., Santa Ana, CA, USA), and 83 eyes of 52 children received MA60AC (AcrySof). At mean follow-up of 18.31 ± 15.04 months, 22.46% of the patients required resurgery for visual axis obscuration. By multiple regression analysis, the rate of visual axis obscuration was affected by the rate of perioperative complications (p = 0.001) and not affected by age (p = 0.98), type of IOL (p = 0.104), or site of IOL implantation (p = 0.603). Conclusion Our findings suggest comparable rates of VAO for children less than 2 years of age receiving different types of hydrophobic acrylic IOLs.

Perfluorocarbon Liquids

The application of perfluorocarbon liquids has been well acclaimed in vitreoretinal surgery. Its unique physical properties make it an ideal intraoperative tool to improve the efficiency and safety of surgical procedures in complicated cases. The main functions of perfluorocarbon liquids in vitreoretinal surgery include relocating and fixing the detached retina, displacing the subretinal and subchoroidal to fluid anteriorly, revealing proliferative vitreous retinopathy (PVR) for further maneuvers, protecting the macula from exposure to chemicals with potential toxicity, and assisting the removal of foreign body. The related clinical applications include retinal detachment with severe proliferative vitreoretinopathy, giant tear, diabetic retinopathy (DR), retinopathy of prematurity (ROP), and posterior dislocated crystalline and intraocular lenses. The application of perfluorocarbon liquids has been expended over the past fewer years. Several PFCLs related ocular inflammations have been observed inin vitrostudies, animal studies, and clinical follow-up. The complete removal of PFCLs is recommended at the end of the surgery in most cases.
