The diagnostic function of OCT in diabetic maculopathy.

Diabetic maculopathy (DM) is one of the major causes of vision impairment in individuals with diabetes. The traditional approach to diagnosis of DM includes fundus ophthalmoscopy and fluorescein angiography. Although very useful clinically, these methods do not contribute much to the evaluation of retinal morphology and its thickness profile.

[Astigmatism after cataract surgery].

Purpose: To evaluate postoperative astigmatism after cataract surgery.

Material And Methods: The studied group consist of 135 patients subjected to cataract surgery; 75 patients (75 eyes) had extracapsular cataract extraction with 12 mm corneoscleral incision (group I); 30 patients (30 eyes) had phacoemulsification with 3.5 mm corneal incision (group II); 30 patients (30 eyes) had phacoemulsification with 3.

Axial length measurements after cataract surgery in adults.

Unlabelled: The purpose of the study was to check the difference in eye axial length before and after cataract surgery and to find out the possible correlation with refraction changes. The axial length was measured by ultrasound before and after cataract extraction with intraocular lens implantation. Keratometry measurements were also performed.

Long-term evaluation of endothelial cell loss after phacoemulsification.

Purpose: To check whether three months' follow-up is sufficient to determine endothelial cell loss after cataract surgery and whether this value depends on preoperative central endothelial cell density.

Methods: A two-year prospective assessment of central endothelial cell density was done in 60 eyes after phacoemulsification. In 30 eyes a 3.
