Background: Posterior capsular opacification is the most common long term complication of modern IOL surgery.
ND: YAGlaserre mains the corner stone of its treatment. In this study, an attempt is made to study the visualout
come and change in the intraocular pressure following Nd: YAG laser capsulotomy and compare the results
between diabetic patients and non-diabetic patients.
Method: This was a prospective study of 100 patients (50 diabetics and 50 nondiabetics), conducted in Khaja
Banda Nawaz Teaching and General Hospital, Kalaburgai. All patients in the age group 45-75 years, attending
the regular OPD who presented with visually significant posterior capsular opacification and were treated with
Nd:YAG laser capsulotomy. Patients were included in the study taking into consideration inclusion and exclusion
criterias. Patients were followed up on first day, first week and the four weeks and the improvement in the BCVA
and the changein IOP (Intra Ocular pressure) were recorded.
Results: All the patients treated for PCO with Nd:YAG laser capsulotomy showed an improvement in visual
acuity. The visual outcome at four weeks (41%had > 6/12) was found to be better than that at first week (34 % had
the same) and first day (16% had the same). The final visualoutcome at 4 weeks was found to be better in nondiabetics
(52% had>6/12) compared to diabetics (30% had>6/12). All the patients showed an increase in IOP at
the first day and first week of follow up and return to near normal of baseline values at four weeks of follow up,
the pattern of change in IOP being similar in both the study groups.
Conclusion: Nd:YAG laser capsule to May effectively improves the visualacuity inpatients with visually significant
PCO. The comparatively poor outcome in the diabetic group can be attributed to the associated retinopathy
changes. Nd:YAGl aser capsulotomy is associated with a transient rise in the intraocular pressure in all patients
which can very rarely remain persistently high.
