Abstract:
Small incision cataract surgery has many advantages such as less induced corneal astigmatism, fast visual recovery, and fast rehabilitation. We had implatned the newly developed Staar AA-4203 foldable silicone IOL in the ag of 100 cataractous eye and followed for at least 3 months (3-0 months, mean 6 months). Silicone IOLs were implanted using a specific injector through 4mm scleral pocket incision after continuous circular capsulorhexis and bimanual phacoemulsification. The lenses were centered well in 99% of eyes. Tear of anterior capsule occurred in one eye (1%), and tear of both anterior and posterior cassule occurred in another one eye (1%) during IOL implatation. The IOL was displaced into the vitreous in the latter eye, which was reoperated. The preoperative and postoperative cornedal astigmatism at 1 day, 1 month, 2 month and 3 month was -O.14 +/- 0.83 D of with the rule astigmatism (WTR), -0.55 +/- 1.06 D of WTR, -0.28 +/- 0.91 D of WTR, -0.07 +/- 0.81 D of WTR, and O.01 +/- 0.84 D of against the rule astigmatism respectively. Uncorrected VA of 1.0 was 35% at postoperative 1 day, 52% at 1 month, 48% at 2 month. Corrected VA of 1.0 was 65% at postoperative 1 day, 87% at 1 month, 88% at 2 month. Inflammatory reaction in the anterior chamber and vitreous had subsided within one or two months without any complications in 99% of eyes. Fibrinous membrane on the suface of IOL occurred in 2 eyes (2%), one of which caused grave sequelae. The results, although it showed early postoperative results, reflected that the above silicone foldable IOL fitted to the small incision cataract surgery guaranteed us the safety and fast visual recovery.
