Abstract
The aim of the work: to study prospectively the changes those occur in the corneal topography and corneal endothelium following microincision cataract surgery using anterior chamber maintainer. Material & Method : 50 patients (50 eyes) with senile nuclear cataract selected at random from patients attending the ophthalmic out patient clinic of Mansoura Ophthalmology Center. The patients were divided into 2 groups, group I included 25 patients (25 eyes) who underwent microincision cataract surgery [with sleeveless phaco tip and ACmaintainer] ,and group II included 25 patients (25 eyes) who underwent conventional phacoemulsification technique. Results : The % of ECL was significantly higher in group II (conventional phaco)[16%] than group I (MICS)[9.05%] all through the postoperative intervals and it stabilizes nearly by 3 months postoperatively in both groups .There is significant difference between both groups in postoperative astigmatism ,(0.99+0.75D among group I) and (1.6+ 1.06D among group II ) after 3 months . However, there is no significant difference in the surgically induced astigmatism in both groups at the same postoperative intervals. Conclusion : Microincision Cataract Surgery have several advantages like easy dealing with hard nuclei with reduced risk of complications, More stable anterior chamber with the usage of the anterior chamber maintainer during MICS, and this enables the surgeons to avoid the post occlusion obstruction (surge) with its effect on the corneal endothelium .Also better control all through the surgery due to working with the two hands.
