Abstract Details

Purpose:

Astigmatism correction analysis using femtolaser arcuate keratotomy in cataract patients

Setting:

191023 St-Petersbrug, Russia, Eximer eye clinic

Methods:

The study included 111 patients (139 eyes) with femtolaser support of cataract surgery or clear lens extraction with arcuate incisions. All investigations were performed prior to surgery, on the 7th day, 1, 3, 6 months and at the last visit. We used following options: main tunnel-2.1-2.0 mm trapezoid, induced astigmatism pawned 0.2D, depth of the arcuate cuts-80% of thickness, incisions were opened immediately. Localization of main tunnel: OD-180º, OS-0º. www.lricalculator.com was used for the nomogramms . Patients were divided into 2 groups - with under 3 months and more than 6 months observation period.

Results:

Mean preoperative astigmatism was 1.46D. After surgery, in 1 month 0.75D and in 3 months 0.55D. The difference between the level of astigmatism in the three month period of observation and last less than 0.1D, within the period of 6 months (0.65D) and over 6 months (0.63D) are statistically reliable. The coefficient of astigmatism reduction is more pronounced in patients over 60 years. UCVA and BCVA at the end of observation group is higher in patients younger than 60 years. There is no difference between UCVA and BCVA in ˂60 years patients, in group aged over 60 is 0.06.

Conclusions:

We observe stabilization of keratometric values in 6 months after femtolaser arcuate incisions. The maximum possible correction of astigmatism using femtoarcuate cuts does not exceed 2.0D. The absolute value of the preoperative astigmatism (up to 2.0D) does not affect the outcome of treatment. Using two incisions for astigmatism correction improves treatment outcomes.
