To compare clinical results between sulcus insertion of intraocular lens(IOL)(Group I) and transscleral fixation of IOL(Group II), visual acuity, spherical equivalent, astigmatism, corneal thickness and intraocular pressure were evaluated, retrospectively. This study was performed on 37patients(43 eyes), who could have been followed up more than 12 months from September 1994 to August 1997. Six mm scleral incision at 12 o'clock position and sulcus insertion of IOL were used with 2 interrupted sutures in cases of aphakia either with some remained anterior capsule or with continuous curvilinear capsulorhexis(Group I, 12 eyes). The same incision and suture method with transscleral fixation of IOL were used in case of aphakia with little remained anterior capsule(Group II, 31 eyes). In Group II, 10-0 polyprolene sutures were buried beneath the scleral flaps at both three and nine o'clock meridians following transscleral fixation of IOL. Uncorrected visual acuity(UCVA) was improved in both Group I and Group II, except for 4 cases of Group II. Lack of improvement of UCVA did not seem to be related to the operative methods. The changes of UCVA, astigmatism, corneal thickness and intraocular pressure were not statistically significant between the two groups. In conclusion, transscleral fixation of posterior chamber-intraocular lens turned out to be safe and effective in certain cases of insecure zonule or posterior capsule, although its surgical procedure is more complicated than that of posterior chamber-intraocular lens implantation into the sulcus without fixation. |
