Abstract Details

Purpose:

To evaluated the refractive and keratometric effect of arcuate keratotomy using femtosecond technology in patients with high post-keratoplasty astigmatism

Setting:

Enaim Medical Center, privet practice

Methods:

Prospective interventional study included 28 eyes of 28 patients after keratoplasty surgery (17 penetrating keratoplasty, 9 intralase enabled keratoplasty). Arcuate depth incision was set to 80% of the minimal graft thickness, with a 60-degree angle. Mean diameter was 5.79 ± 0.32 according to the graft size. Patient evaluation included LogMAR best correct visual acuity (BCVA), refraction, keratometry and full eye examination.

Results:

Both UCVA and LogMAR BCVA improved after surgery. Preoperatively the mean LogMAR BCVA was 0.3 ± 0.38, and it was improved by one line to 0.2 ± 0.23 (P=0.19). The mean refractive astigmatism was -8.75 ± 2.80 D (range -4.5 to -15 D) declined after surgery at 3 months follow-up to -4.31 ± 2.30 D (P<0.001) and remained stable up to the end of the follow up (-5.50 ± 1.25 D, P=1.00). The mean keratometric value increased by 1.08 D (P<0.001). No complication or adverse effects were demonstrated during follow-up period

Conclusions:

Arcuate keratotomies performed with the femtosecond laser were both effective and safe in reducing post-keratoplasty astigmatism
