Abstract

Purpose: Corneal Endothelium Outcome After Torsional Phacoemulsification surgery. Desigen: prospective randomized study. Methods: This is a prospective study that was performed on 20 patients to estimate postoperative corneal endothelial outcome after cataract surgery performed with torsional phacoemulsification in senile cataracts. The current study has been conducted at Al-Azhar University Hospital Asyuit. Results: This is a prospective study that was performed on 20 patients to estimate postoperative corneal endothelial outcome after cataract surgery performed with torsional phacoemulsification in senile cataracts. Preoperative data including age, sex and grading of nucleus are Presented in Table (3). The Age group ranges from 55-65 years, including 12 males & 8 Females, all have Nuclear cataract grade II-III. In our trial we also conducted a more detailed study about the corneal endothelial cells as regard, Endothelial cell Count (Endothelial density) (CD), Average cell size (AVE), Maximum cell size (MAX), Minimum cell size (MIN), Coefficient of variation in cell size (CV), Standard deviation in cell density (SD), Pachymetry (PACHY), Best corrected visual acuity (BCVA), as well as the Percentage of the hexagonal cells (6A). Conclusion: Our results indicate that the torsional phacoemulsification is a safe method of removing uncomplicated senile cataract with less endothelial cell loss. Torsional phacoemulsification has the advantage of reducing UST as well as effective energy used. Phaco duration was the most significant intraoperative factor affecting the corneal endothelium. So Specular microscopy is a useful tool in preoperative assessment of cataract patients especially in cases undergoing phacoemulsification. This study is limited by a small sample size in hard cataracts. Nevertheless, the findings have meaningful clinical relevance to support the efficiency and safety of torsional phacoemulsification in medium density cataracts.
