Abstract Details

Purpose:

To report our initial clinical experience with the use of Precision Pulse Capsulotomy device which is a new capsulotomy technology that works on the principle of converting very fast electrical pulses into mechanical energy in millisecond timeframe.

Setting:

National Institute of Ophthalmology, Pune

Methods:

123 eyes of 99 consecutive patients who underwent phacoemulsification with precision pulse capsulotomy through a 2.8 mm clear corneal incision were studied. The size, shape of capsulotomy and intraoperative and postoperative complications were noted. Visual outcome, IOL stability and signs of capsular opacification/contraction were evaluated at 3 and 6 months.

Results:

The mean age of our patients was 49.5 ±7.77 years. Complete, circular capsulotomy averaging 5.5 mm diameter was achieved in 117 out of 123 eyes. In 7 eyes we experienced complications like capsulorhexis tear(n=6) and inadvertent iris capture (n=1).Probe malfunction occurred in 6 cases. Stable intracapsular intraocular lens (IOL) fixation and centration was achieved in all eyes. None of the eyes had any significant posterior capsular opacification or capsular contraction at 3 and 6 months. In 1 eye anterior capsular opacification at the capsulotomy edge was noted at 6 months

Conclusions:

Precision Pulse Capsulotomy is a useful device for achieving a perfectly round capsulorrhexis. However it has a learning curve and subincisional area can have skip areas leading to torn capsulorhexis. Also the possibility of capsular tag and its extension should be kept in mind. Special care should be taken in initial cases and while operating on eyes with poorly dilating pupil and mature cataracts.
