Purpose: To compare preoperative estimated refraction and postoperative actual refraction after posterior chamber lens implantation with CORNEALⓡ (Pringy, France) lens in high myopia during cataract surgery.
Methods: The 41 eyes (26 cataractous patients in high myopia) were evaluated from April 2000 to December 2004. Postoperative 1 week, 1 month, 3 months, 6 months, actual refraction was measured objectively by autokerato-refractometer and manifest refraction. And preoperative predicted refraction was estimated using SRK/T formula. The difference between preoperative predicted refraction and postoperative actual refraction was verified using one way ANOVA, the average difference verification. And the significancy was estimated by Duncan.
Results: Postoperative 3 months, the spherical equivalent seemed to be hyperopic. 1 week after surgery, the spherical equivalent was －2.76±0.26 D, 1 month, 3 month, and 6 month after surgery, the spherical equivalent was 2.24±0.21 D, －1.89±0.20 D, and －1.73±0.23 D. As time goes by, it tended to be moved hyperopia significantly (p＜0.05).
Conclusions: Postoperative predicted refraction in high myopia implantated with CORNEALⓡ lens during cataract surgery seems to migrate hyperopia to some degree compared to the preoperative estimated refraction.
