Purpose:

To determine the refractive and keratometric predictability, stability and efficacy of Femtosecond laser Astigmatic keratotomy for high astigmatism in virgin eye

Methods:

In a prospective interventional case series, 6 eyes of 3 consecutive patients whose astigmatism was non correctable with spectacles were enrolled. The LDV Femtosecond Laser performed using Paired arcuate incisions based on nomogram. The value and location of the steep meridian were determined by evaluation of refraction, and topographic values. Main outcome measures were preoperative and postoperative manifest refraction, uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity(BSCVA) topographic astigmatism and keratometery. Our postoperative follow up extended to 3 months after surgery.

Results:

The mean age of the patients was 34±5.3 years old (range: 22-48). Mean uncorrected logMAR BSCVA and UCVA improved from preoperative values of 0.22±0.05 and 0.38 ±0.09 to 3-month values of 0.19±0.06 and 0.43±0.08, respectively. Mean manifest astigmatism was 5.25±0.68 diopters (D) preoperatively and 1.95±0.22 D at 3 month after surgery. The mean Spherical equivalent before and after the procedure were -0.21±1.6 D and -1.1±1.83 respectively. The mean values of Topographic astigmatism before and after the surgery were 4.24±0.51 D and 1.36±0.22 D respectively. The mean values of preoperative and postoperative topographic keratometry were 44.15±1.00 D and 44.55±1.03 D respectively. No complication was noted in the follow up visits.

Conclusion:

Femtolaser assisted astigmatic keratotomy is an effective treatment for high astigmatism in virgin eye with an encouraging refractive predictability. There is some myopic shift after femtolaser assisted astigmatic keratotomy.
