Impact of Phacoemulsification Cataract Surgery to Number of Corneal Endothelial Cells: A Descriptive Study

Abstract

The main optical structure of the eyes is the lens and corneal because lens with the cornea, focuses image of the visual world onto the retina. Both of the main optical structure is affected by age, it affects the corneal endothelial cells and transparency of the lens. By aging the corneal endothelial cells decrease and the lens loses its transparency then the cataract appears [1,2]. it is known that cataract surgery effecting the corneal endothelial cells number. The surgery will be decreasing the corneal endothelial cells number. The severity to which endothelium is affected depends on many factors, such as phacoemulsification time and energy, surgical technique, anterior chamber depth, and use of ophthalmic viscoelastic devices (OVDs) [3]. A total of 52 people with cataracts were enrolled in this descriptive investigation. The study is included 52 eyes. Ages ranged from 43-77 years, with a mean age of 57,7 years. From this study 59,6% were men and the rest are women, which 79% were diagnosed with immature cataract, and 21% were diagnosed with mature cataract. It was found that 86,5% of eyes experienced a decrease in the number of corneal endothelial cells after cataract phacoemulsification surgery. The mean of corneal endothelial density pre surgery is 3126 cells/mm2 ± 246,1 and the mean of corneal endothelial density post-surgery is 3029 cells/mm2. The range of surgery time is 6-30 minutes. With the mean time of surgery 13,7 ± 5,8 minutes. From 52 eyes there are 45 eyes with corneal endothelial cells loss 7 days after surgery, with the mean of corneal endothelial cells loss after cataract phacoemulsification surgery are 152,3 ± 68 cells/mm2, the percentage mean was 6%, and we found decreasing in central corneal thickness, corneal endothelium density, hexagonality and increasing coefficient of variety.
