| Abstract;We report clinical evaluation of the posterior capsule opacification (PCO)-preventive effect of intraocular lens (IOL) material and edge sharpness, using new quantitative methods. Each of 90 eyes that underwent cataract surgery received IOLs of different edge design (sharp-edged silicone IOL, optic diameter 6.0mm (AQ310NV,Canon Staar)), round-edged silicone IOL, optic diameter 6.0mm (SI40NB,AMO) or IOLs of different materials (acrylic IOL (MA60BM, Alcon) and silicone IOL (AQ310NV)). Each type of IOL was inserted into 30 eyes. Patients were examined at 1,3,6 and 12 months after surgery. PCO was assessed with an anterior eye segment image analyzer (EAS-1000, NIDEK) in the retroillumination mode, using Scion Image (Scion Inc.) image analysis software. Results showed that PCO onset with the sharp-edged silicone IOL was significantly lower than that with the round-edged silicone IOL. However, there was no significant difference in PCO onset or suppression between the sharp-edged silicone and acrylic IOLs. The present methods enable objective assessment of clinical PCO. It is surmised that the sharp-edged IOL prevents PCO. (author abst.) |
