ABSTRACT
PURPOSE: To evaluate the onset of retinal detachment (RD) in eyes with phacoemulsification and post chamber lens (PE & PCL) implantation. METHODS: We retrospectively analyzed 3023 eyes that had undergone clear cornea incision and PE and PCL implantation and 116 eyes that had undergone scleral incision and PE and PCL implantation. They had been operated from January 1995 to December 2000 by one surgeon and followed up for 4 years or more. RESULTS: Eighteen eyes (0.57%) of the 3139 eyes developed pseudophakic RD within a mean period of 663 days. In the scleral incision group, there were 4 cases of pseudophakic RD (3.4%) of 116 eyes developed in a mean period of 185.2 days. In the clear cornea group, there were 14 pseudophakic RD eyes (0.46%) of the 3023 eyes and the mean period was 799 days. Of these, 3 eyes made up the intraoperative complication group with a mean period 205.6 days. But in the group of cases with no intraoperative complications, the mean period was 962 days. CONCLUSIONS: In high myopic eyes, retinal detachment developed in the earlier postoperative period and at a higher rate than those of non-high myopic eyes after PE and PCL implantation.

PURPOSE: To report the technical effectiveness, outcome, and incidence of complications of combined clear cornea phacoemulsification with intraocular lens implantation and pars plana vitrectomy. METHODS: Single-center prospective, non-comparative, consecutive case series. Twenty-three eyes of 23 patients underwent combined clear cornea phacoemulsification and pars plana vitrectomy for various vitreoretinal disorders due to cataracts by a single surgeon between July 2003 and August 2004. Surgical feasibility, intraoperative and postoperative complications and outcome of clear cornea incisions in all combined procedure were evaluated. RESULTS: No significant adverse effect of clear corneal wound on pars plana vitrectomy procedures was noted in any of the patients. Operatively and postoperatively, no significant complications related to clear corneal wound were noted, even with the variations of pars plana vitrectomy procedures for cases with and without gas-fluid exchange and intravitreal tamponade. CONCLUSIONS: Clear corneal incisions is a safe and more reasonable alternative in combined phacoemulsification with intraocular lens implantation and pars plana vitrectomy. For a more comprehensive conclusion, a comparative study with scleral tunnel incisions may be necessary.

IncidenceABSTRACT
The short-term changes in corneal astigmatism and visual acuity after phacoemulsification with foldable intraocular lens implantation through a 3.2mm temporal clear corneal incision (group 1) and these through a 3.2mm superior scleral incision(group 2) were compared.Corneal topographic measurement were obtained preoperatively and at poeroperative 1 day, 2 months. Scalar and vector astigmatism in group 1 and group 2 were compared by simple subtraction method, Cravy method and Holladay method.The surgically induced astigmatism in both groups showed no difference in with-the-rule change(0.57D-0.10D) and uncorrected visual acuity also showed no different results in both groups. In the group 1, preoperative with-the-rule astigmatism were changed 0.18D toward with-the rule and preoperative against-the -rule astigmatism were shifted 0.64D toward with-the-rule direction.Conclusively. both incisions offered satisfactory short-term astigmatic results and rapid visual rehabilitation and change of astigmatism in the wyws with preoperative against-the-rule astigmatism was greater than those with peroperative with-the-rule astigmatism in temporal clear corneal incision group.
