Non-Sutured phacoemulsification versus conventional extracapsular cataract extraction incision. Effect on postoperative astigmatism

The aim of this retrospective study is to compare the effect of conventional incision for Extracapsular Cataract Extraction and intraocular lens implantation, to a non sutured small corneal incision for Phacoemulsification, with implantation of foldable intraocular lenses or the wound widened to allow the insertion of a rigid intraocular lens on postoperative astigmatism. The study involved 243 patients.189 patients were operated for Extracapsular Cataract Extraction, 54 patients underwent phacoemulsification. Uncorrected and best corrected visual acuity were determined before surgery as well as one week and monthly for 6 months after surgery. Early significantly lower astigmatism was found in phacoemulsification group. Starting from the first postoperative month till the end of the sixth month, the astigmatism was higher in the Extracapsular, group. Uncorrected and best corrected visual acuities were better in the phacoemulsification group all through the follow up periods. Phacoemulsification results in early significant lower astigmatism, better uncorrected and corrected visual acuity, when compared to Extracapsular cataract extraction. Thus proving a better refractive advantages and early visual rehabilitation

Conjunctival grafting and cytotoxic drugs for advanced and recurrent pterygia

Although there are many surgical methods for treating pterygium, there are also several complications, the most important of which is recurrence, which usually associated with increased conjunctival inflammation, induced astigmatism and aggravated preoperative symptoms. Repeated surgery often worsens the situation, as loss of conjunctival tissue and scarring can result in obliteration of the fornices and mechanical restriction of ocular movement. In this retrospective study, forty two cases were operated for advanced primary and recurrent pterygium. In twenty six cases excision and free conjunctival auto graft taken from superio-temporal bulbar conjunctiva were done, in sixteen cases excision, application of mitomycin c and sliding flap graft were done. In one case [3.8%] there was graft failure, that occurred in the first post operative week, in three cases out of the grafted group [8.7%] recurrence of the Pterygia was reported within three months postoperative, recurrence occurred in one case [6.3%] in the sliding flap group
