RESUMO

23 eyes of 23 patients who underwent conventional vitreoretinal surgery with high specific gravity perfluorocarbon liquid, perfluorophenanthrene, for complicated retinal detachment were evaluated retrospectively. Preoperative vitreoretinal findings showed grade C2 PVR in 4 eyes and C3 in 1 eye and C4 in 10 eyes and C5 in 8 eyes. As a result, 17 eyes(74%) showed anatomical success, completely reattached in 15 eyes, partially reattached in 2 eyes, and 12 eyes(52%) showed functional success (corrected visual acuity 5/200 or better). Follow-up period was over 6 months in all cases. Postoperative complications includes keratopathy in 6 eyes, hypotony in 5 eyes, cataract in 2 eyes, transient vitreous hemorrhage in 1 eye, acute increased IOP in 1 eye, posterior synechiae in 1 eye, cystoid macular edema in 1 eye, and pupillary membrane in 1 eye. Consequently, perfluorophenanthrene can be used beneficially in yield of surgical field and mechanical stabilization of retina in complicated retinal detachment surgery.

RESUMO

Long term changes in corneal astigmatism after cataract surgery were evaluated. Phamemulsification with 7mm limbal incision(Group 1) was performed in 68 eyes and ECCE with 101mm limbal incision(Group 2) in 73 eyes. Follow up period was up to 5 years (mean 3.3 years), and the astigmatic change was analysed by Algebraic method. In most cases, postoperative astigmatigm was stabilized at 3 months but showed continuing against-the-rule change up to 5 years. Group 2 and above 60 years of age group showed more against-the-rule change at 5 years follw up although there was no significant differences between groups, up to 2 years. Preoperative against-the-rule group and less than 4 diopters of with-the-rule astigmatism group at 1 week postoperatively developed more against-the-rule change. Diabetic patients showed slightly more shift to against-the-rule astigmation than non-diabetic patients. As a conclusion, corneal astigmatism shifted toward against-the-rule up to 5 years after the cataract surgery continuously and affected by incision length, age of the patients, preoperative astigmatism and diabetes. Thus, surgical modifications would be considered by the patients' status.
