Objective: To evaluate the visual and refractive results, the changes in contrast sensitivity and the incidence of posterior capsule opacification (PCO) after implantation of UltraChoice 1.0 ThinOptX (ThinOptX Inc.) IOL and conventional acrylic foldable IOL (AcrySof MA30AC) in fellow eyes.
Material and Methods: Fifty eyes of 25 patients were randomized into two groups prospectively: In Group 1 microincisional phacoemulsification and ThinOptX IOL implantation were applied in one eye and in Group 2 conventional phacoemulsification and AcrySof IOL implantation were applied in the fellow eye. Uncorrected (UCVA) and best-spectacle corrected visual acuity (BCVA), surgically induced astigmatism (SIA), contrast sensitivity and the incidence of PCO were observed in the two groups and compared between of them.
Results: Mean follow-up period was 12.8 ± 1.5 months (range 11 to 14 months). In the last follow up examination UCVA and BCVA were significantly lower (p< 0.05) and PCO scores were significantly higher in Group 1 (p< 0.001). Although SIA was lower in Group 1, the difference was not statistically significant. Contrast sensitivity in higher spatial frequencies were significantly lower in Group 1 in the 6th month and 12th month visits (p< 0.05). Capsular contraction was seen in 3 eyes (12%) in Group 1 whereas there was no capsular contraction or phimosis in Group 2.
Conclusions: Long term evaluation of ThinOptX IOL concludes with an increased rate of PCO and diminished resistance to capsular contraction than AcrySof IOL and is associated with a decrease in visual performance. The poor after cataract performance of these rollable lenses shows that micro-phacoemulsification and ThinOptX IOL implantation is not as effective as conventional phacoemulsification and AcrySof IOL implantation in the long term.Keywords: Cataract extraction; contrast sensitivityTurkiye Klinikleri J Ophthalmol 2007, 16:20-27
