Abstract Details

Purpose:

To describe various types of anterior capsular tears and an early diagnostic ‘Flap Motility’ sign for posterior capsular rupture following posterior extension of radial tears.

Setting:

Dr Om Parkash Eye Institute, Amritsar, India.

Methods:

A evaluation of 4331 eyes undergoing phacoemulsification in a private practice setting from April 2015 to February 2016. Twenty six consecutive cases of anterior capsular tears were included. Morphological features of anterior capsular tears and resultant complications were evaluated. Parameters studied were surgical step during which the tear occurred, shape of tear, its extension in relation to the equator and flap nature and motility in tear extending upto equator. Main outcome measures were motility and nature of flaps in anterior capsular radial tears and the relation to posterior capsule rupture.

Results:

Based on shape, extent and angulation, anterior capsular tears were categorized into 5 types i.e. Type I - Pre equatorial radial tear (26.92%), Type II - Post equatorial radial tear (3.85%), Type III - Argentinean flag sign pre equatorial tear (57.69%), Type IV - Argentinean flag sign post equatorial tear (7.69%) and Type V - Mini punch (3.85%). Flaps were either seen to be everted and fluttering or inverted and non-fluttering. In all cases with everted, fluttering flaps no posterior capsular rupture (PCR) was observed while in cases with inverted, non-fluttering flaps a PCR was observed (p< 0.05).

Conclusions:

Everted and fluttering flaps of the anterior capsular tears indicate pre-equatorial tear while inverted and non fluttering flaps indicate posterior capsule rupture following tear extension beyond the equator.
