All angle closure patients were on two or more topical glaucoma medications and had prior laser iridotomy. Eyes underwent clear lens extraction by phacoemu - lsification with intraocular lens implantation. ·RESULTS: All five patients in this case series carried the diagnosis of angle -closure glaucoma and had uncontrolled IOP prior to surgery despite topical medications. After clear lens extraction three of the cases had good IOP control (IOP 【22mmHg) without the need for topical medications. In one case the IOP was better controlled after surgery, however, topical medications were required. The desired IOP was not met in one case despite restarting maximum topical therapy. ·CONCLUSION: This case series suggests that there may be a role for therapeutic clear lens extraction in select cases of angle-closure glaucoma.展开更多

The preoperative refraction values were +17.75DS -1.50DC × 168° for the right eye and +17.25DS -0.75DC × 8° for the left eye. The uncorrected visual acuity (UCVA) was 20/200 bilaterally and the spectacle-corrected visual acuity (BSCVA) was 20/50 bilaterally. One year after Artisan iris-fixated IOL implantation, bilateral BSCVA was 20/50 with a refraction of +1.25DS -0.75DC × 13° for the right eye and +1.50DS -1.00DC × 55° for the left eye. The outcomes of an Artisan iris-fixated IOL implantation followed to CLE with PC-IOL implantation were encouraging for the correction of extreme hyperopia. Long term follow-up examinations were necessary for further determination of the efficacy and safety of this combinational procedure.展开更多
