PURPOSE
We compared the apparent accommodative power of acrylic intraocular lens(IOL) with silicone IOL after implantation of IOL into the bag. METHODS: In 36 senile catatact patients(40 eyes)visited St. Mary's hospital from July 1999 to June 2000, the IOL was inserted into the capsular bag after continuous curvilinear capsulorhexis. All of them were over 60 years old. We checked corrected visual acuity, pupil diameter and apparent accommodative power by accommodometer(AA2000, Nidek, Japan) preoperatively and 1 day, 1 month, 2 months after surgery. The used IOLs were two groups, ones are Acrysof (Alcon, U.S.A.) in 20 eyes and the others are Soflex (Chiron vision, U.S.A.) in 20 eyes. RESULTS: The investgation revealed that the apparent accommodative power reached its peak at 1 month after surgery. There was no stastically significant difference(p>0.05) between acrylic IOL and silicone IOL in apparent accommodative power at 2 months after surgery. CONCLUSIONS: The analysis revealed that the pupil size had significant negative correlations with apparent accommodative power at each other group, whereas corrected visual acuity and refraction error showed no relationship with apparent accommodative power. |
