Abstract Details

Purpose:

To asses the safety and efficacy of Deep Anterior Lamelar Keratoplasty (DALK) in patients with corneal complications after radial keratotomy (RK).

Setting:

Instituto Oftalmológico Fernández-Vega. Oviedo. Spain.

Methods:

Observational retrospective study of patients treated with DALK operated at our centre between October 2010 and August 2013. All the patients had RK prior to 1990 at other centers. They all showed corneal manifest disorders (excessive central flattening or peripheral ectasia) along with progressive loss of visual acuity. The study comprises 7 eyes from six patients with a minimum follow-up after keratoplasty of 6 months.

Results:

Mean uncorrected distance visual acuity (UDVA) at their first post-op visit was 0.2 and 0.5 (decimal) with their correction (DCVA) and a mean flat-keratometry of 31.3 diopters (D). In order to achieve patient's refractive and visual rehabilitation it was necessary to associate, depending on the case, lensectomy, lens exchange, epicrystalline lens implantation or corneal additive surgery using intrastromal ring segments. At the end of the procedures, the mean flat-k was 42.5 D, with a mean UDVA of 0.4 and DCVA of 0.7 (decimal).

Conclusions:

The DALK technique associated with simultaneous or deferred refractive surgery is a safe and effective option for the treatment of disabling keratometric disorders in patients who previously underwent RK. FINANCIAL INTEREST: NONE
