PURPOSE
To evaluate the effects of ICL implantation on angle structures, intraocular pressure (IOP) and pupil diameter. METHODS: A Staar implantable contact lens (ICL) was implanted in 81 eyes of 43 patients with spherical equivalent over -6D. Gonioscopy was done 1 day after laser iridotomy and 6 months after ICL implantation and postoperative changes in gonioscopic findings were evaluated. Also IOP and pupil diameter were examined. RESULTS: There were occlusion or narrowing of the LI opening site in 10 eyes (12.3%). Width of angle was wide over 30 degrees in all cases but that was narrowed under 20 degrees in 16 eyes (19.8%) at postoperative 6 months. The mean pigmentation was 2.11 in inferior, 0.47 in nasal, 0.22 in temporal and 0.18 in superior angle at 6 months postoperatively by semiquantitative method (Grade 0~4). There was decrease of pigmentation in nasal and temporal angle but no change in inferior and superior angle after ICL implantation. There was temporary increase of IOP at 1 week and 1 month postoperatively due to steroid eye drops but returned to preoperative level and maintained until the 6 months postoperatively. There was significant decrease of pupil diameter at postoperative 1 and 3 months but returned to the preoperative level at postoperative 6 months. There was no evidence of pigment dispersion syndrome and pigmentary glaucoma. CONCLUSIONS: ICL implantation caused the narrowing of width of angle but did not increase trabecular pigmentation. We expect that ICL implantation is safe about pigment dispersion syndrome and pigmentary glaucoma. |
