تقييم تغيرات ثخانة طبقة ألياف العصب البصري حول الحليمة في العيون الحسيرة باستخدام التصوير المقطعي التوافقي البصريّ

Abstract EN

Background & aim : The aim of this study is to examine the influence of Capsulotomy using NeodymiunDoped Yttrium-Aluminum-Grant (Nd:YAG) on refraction.

Methods : Thirty-Five pseudophakic eyes with posterior capsule opacification of 35 patients were included.

Nd:YAG laser posterior capsulotomy was performed using Nd: YAG Laser NIDEK YC1600.

Patient’s’ refraction was measured before treatment, as well as after the treatment at 1 week and 3 months.

Automated refractometer was used at the department of Ophthalmology, Almouassat University Hospital, Damascus, Syria.

Data were analyzed statistically.

Results: Mean age was 68.1 years ± 9.61 ( range : 46-82 years).

The average interval from the cataract surgery to Nd:YAG laser capsulotomy was 14 months (range 8-20 months).

The mean spherical equivalent (SE) before treatment was -0.55 D ±0.91D, at 1 week after the treatment -0.45 D ±0.88D and at 3 months after the treatment -0.48 D ±0.90D.

The changes in spherical equivalent were statistically insignificant.

There were statistically significant differences between cylindrical power refraction before treatment -3.20 ±1.05 and at 1 week, 3 months after the treatment -1.51 ±1.15, -1.61±1.23 respectively.

Conclusion : Nd:YAG laser capsulotomy is an effective method of treatment of posterior capsule opacification.

Nd:YAG laser capsulotomy did not significantly change spherical equivalent, it led to cylinder change at 1 week and 3 months
