Abstract Details



Purpose:

To evaluate and measure induced astigmatism after phacoemulsification with femtolaser assisted corneal incisions .

Setting:

S. Bassiano Hospital, Dept. of Ophthalmology, Bassano del Grappa, Italy

Methods:

A series of 20 eyes of 10 patients were randomly selected to undergo cataract surgery. Two clear corneal incisions were performed by using femto-laser (Abbott). Side port was 1.3 mm x 1.0 mm and 1/3 depth of corneal thickness at 2 o’clock site. The main incision was 2.2 mm x 1.1 mm at 10.30 o’clock position. Capsulorexhis was performed by using forceps for MICS and phacoemulsification by using a dual-pump machine with transversal ultrasound technology (Signature, Abbott). For IOL implantation a 2.2 mm cartdrige was used (Platinum, Abbot). Astigmatism was measured by using IOL Master (Carl Zeiss) preoperatively and 3 months after surgery. Induced astigmatism was calculated by using Surgically Induced Astigmatism (SIA) calculator available on web-site “doctor-hill.com”.

Results:

induced astigmatism after this surgical procedure was by 0.28ḟ0.06 D.

Conclusions:

Induced astigmatism after femtolaser corneal incision by 2.2. mm and MICS phacoemulsification was significantly stable and predictable due to the low standard deviation. This procedure could make postoperative astigmatism changes more predictable in MICS surgery especially for toric IOLs implantation
