ABSTRACT
The accuracy of intraocular lens power calculation in cataract surgery depends on three factoraccuracy of the biometric data[axial length, corneal power, predicted pseudophakic anterior chamber depth], accuracy of manufacturer of IOL power quality, and accuracy of the IOL power formulas usedto obtain desired lens power. We retrospectively analyzed 27 patients[40 eyes] who had taken 3.2 millimeterscleral tunnel incision and been implanted with Silicone IOL. We evaluated the correlation between pseudophakic anterior chamber depth and preoperative lens thickness. And, we calculated the ratio of anterior and posterior distance from the central point on the presumption that there is the central point remaining constant despite of thickening of lens. The preoperative mean lens thickness was 4.47 +/-0 .4 9 mm. The change of anterior chamber depth was significantly increased according to the lens thickness at postoperaitve 3months[r=0.57, p<0.01]. The mean ratio of anterior and posterior distance from central point was 0.290.71. This result suggests that the postoperative anatomical center of IOL will change more posterior as increasing preoperative lens thickness. And we concluded that we would more exactly predict postoperative pseudophakic anterior chamber depth considering the preoperative lens thickness if the ratio of lens thickening was constant.
