Microincisional cataract surgery and Thinoptx rollable intraocular lens implantation

Microincisional cataract surgery is a safe procedure with a very short learning period for an experienced cataract surgeon and rollable ultrathin intraocular lenses eliminate the need for enlargement of corneal incision. The purpose of the study was to evaluate the safety and efficacy of cataract surgery through a corneal microincision and implantation of rollable ultrathin intraocular lenses. The setting was Dokuz Eylul University Medical Faculty, Ophthalmology Department, Izmir, Turkey and SSK Okmeydani Hospital, Ophthalmology Clinic, Istanbul, Turkey. Ninety eyes in 85 patients were operated on through clear corneal microincisions with sleeveless phacoemulsification and rollable intraocular lenses were implanted. Forty-six of the patients were men and 39 were women between the ages of 27 and 83, with a mean of 51 years. Two eyes had atrophic senile macular degeneration, 4 eyes had nonspecific retinal pigment epithelial changes with chorioretinal atrophy, and 4 patients had diabetes mellitus without retinopathy. Three eyes had posterior capsular opacifications of unknown etiology. Two eyes had primary open angle glaucoma (PAAG) with cup to disc ratios of about 0.5. Three eyes had dense nuclear sclerosis of grade 4 with very low visibility of retinal structures. Other patients had no ocular or systemic pathology other than nuclear/corticonuclear cataract of grade 2-3. Uncorrected and best spectacle-corrected distance and near visual acuities, keratometric values, and refractive status were noted preoperatively and 1 week, 1 month, and 6 months postoperatively. Statistical analysis of keratometric changes between preoperative and postoperative findings was performed using the paired samples t test. At 6 months postoperatively, 1 patient had a best spectacle-corrected visual acuity (BSCVA) of 0.2, the patient with atrophic senile macular degeneration. The rest of the eyes achieved a BSCVA of 0.63 or better. At 6 months postoperatively, 55 (61.11%) eyes had uncorrected visual acuities (UCVA) equal to or better than 0.8 and 83 (92.22%) eyes had BSCVA equal to or better than 0.8 according to the Snellen chart. The mean postoperative corneal astigmatisms at 1 week, 1 month, and 6 months were 0.69+/-0.43 D, 0.66+/-0.46 D and 0.65+/-0.48 D respectively. Statistical analysis revealed a significant change in corneal astigmatisms at the 1st week visit (p0.05) compared with preoperative findings. Based on the limited
