Abstract

Objective: Preoperative anterior segment optical coherence tomography in assessing posterior polar capsule integrity.

Method: A prospective observational study of 40 eyes of 25 patients. Patients with posterior polar cataracts undergoing elective cataract surgery were planned for ASOCT [Copernicus Revo (OCT NX700 Optopol technology) and the IOL master 700 (Carl Zeiss Meditec AG, Jena, Germany)] for determining the posterior capsular integrity and planned for phacoemulsification, by two surgeons during the period of January 2019 to December 2019. Posterior polar cataracts were categorized: Type 1- “continuous”; Type 2: abrupt, Type 3: “dehiscent”.

Results: A total of 40 eyes (25 patients) were included. 30 eyes (75%) were bilateral (15 patients) and 10 eyes (25%) were unilateral patients. ASOCT findings noted were, type-1 PPC were observed to be 85% (34 eyes) and 70% (30 eyes) equally detected with both the IOL master 700 and the Optopol ASOCT, Type-2 PPC were 12.5% (5) and 15% (6) of the cases and type-3 PPC were 2.5% (1) with the IOL master 700 and 10% (4) with the Optopol Revo ASOCT. The sensitivity and specificity for the IOL master 700 for predicting the PPC integrity was 90.32% and 66.27% each, and for the Optopol REVO ASOCT was 96.77% and 90% each. Intraoperatively, posterior capsular rent was noted in type-3 PPC, 2 cases (5%).

Conclusion: AS-OCT provides a relevant insight for predicting preoperative PC deficits thus enabling better surgical planning and in anticipating PCR.
