Abstract Details

Purpose:

To evaluate the refractive results of excimer laser ablation treatment in forme fruste keratoconus patients with myopic and astigmatic refractive error.

Setting:

Refractive Surgery Department

Methods:

Seventy seven eyes of 39 patients files with forme fruste keratoconus disease underwent excimer laser(LASIK, PRK) procedure over 10000 refractive surgery patients were evaluated. All eyes were observed more than 7 years after the surgery. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction spherical equivalent (MRSE), topographic findings were recorded.

Results:

Mean UDVA improved from 0.09±0.15(Snellen) pre-operatively to 0.92±0.31 after early postoperative follow up and to 0.16±0.26 in long term follow up( 8.82 ±1.8 years)(P=0.0001)(P=0.025). Mean CDVA improved from 0.74±0.30 pre-operatively to 0.98±0.22 after early postoperative follow up and to 0.35±0.37 in long term follow up (P=0.0001) (P=0.002). Average Keratometry values reduced from 45.12±2.47 D pre-operatively to 39.82±3.44 D after early postoperative follow up and to 45.82±5.47 D in long term follow up(P=0.0001)(P=0.384).

Conclusions:

Excimer laser ablation treatment for forme fruste keratoconus patients resulted in ectasia after long term follow up. Combination with crosslinking or separately different refractive surgeries may result in better outcomes for forme fruste keratoconus patients.
