Background. Ultrasound energy during phacoemulsification can cause mechanical trauma to corneal endothelium which leads to prolonged postoperative recovery. Several studies have reported conflicting results of corneal changes after phacoemuslification in diabetic versus non-diabetic patients. We aimed to assess corneal edema recovery and compare best corrected visual acuity (BCVA) after phacoemulsification in patients with diabetes mellitus type 2 versus patients without type 2 diabetes. Methods. The study included type 2 diabetic and nondiabetic patients who underwent phacoemulsification between November 2018 and May 2019. Assessments of corneal edema recovery were done preoperative and on postoperative day 1, after 1 week and after two months. BCVA were taken preoperative and postoperative after 1 week and 2 months after the surgery. Results. There was no significant difference between groups in corneal status on checkup examinations. Corneal edema recovery was equal between the patients with and without diabetes mellitus type 2. No significant difference in mean BCVA was observed between the studied groups after the operation. Conclusion. Considering the use of modern technology in cataract surgery, there was no difference in postoperative results between non-diabetic and type 2 diabetic patients.

Purpose: Demonstrate the possibilities of successful surgical treatment of patients with late complications after filtering surgery. Methods: This study shows patients who have developed a cystically dilated or leaking filtering bleb in the late post‐surgical period after filtering surgery. Excision of the indadequate filtering bleb has been performed in the patient with a cystic bleb. After the failure of less invasive methods of treatment, we have proceeded to bleb revision with a scleral patch graft in the patient with a leaking bleb. Results: Patients treated with either bleb excision or scleral patch graft showed no signs of neither hypotonia nor secretion during the six‐months post‐surgical period. During that period, complicated cataracts developed. After cataract surgery the function of the filtering bleb was preserved. Conclusions: During the several months of patients' follow‐up, reconstructive methods of treatment have shown to be successful in high‐risk patients who have developed post‐surgical complications in the form of leaking or inadequate filtering bleb.

Aim: To determine the effect of nuclear opalescence (NO) on intraoperative parameters during phacoemulsification using the WhiteStar Signature® PRO and to show the impact of preoperative and intraoperative parameters on postoperative corneal edema.Methods: This prospective study included 267 patients selected to undergo phacoemulsification using the WhiteStar Signature® PRO system at the Department of Ophthalmology of the General Hospital “Dr Josip Benčević”, Slavonski Brod, Croatia. NO was graded using the Lens Opacities Classification System III. Preoperative parameters were age, sex, NO and preoperative central corneal thickness. Intraoperative parameters of phacoemulsification included in the study were ultrasound time (UST), phaco time using Ellips FX technology (EFX) and average phaco power (AVG). Patients were followed up on postoperative days 1 and 7 and after two months. The state of the cornea was noted in each follow-up.Results: There was a statistically significant increase of intraoperative parameters with NO. Postoperative corneal edema depended on all measured intraoperative parameters (UST, EFX and AVG, all p < .001), patient’s age (p < .05) and NO (p < .001) on postoperative day 1, while on postoperative day 7, it depended on UST (p = .011) EFX (p = .012) and NO (p < .05).Conclusion: Older patients, higher grade of NO and amount of energy consumed during phacoemulsification using the WhiteStar Signature® PRO are predictive factors for severity of transient corneal edema. We found this information important for better preoperative planning of phacoemulsification, as well as for better postoperative results.
