Abstract Details

Purpose:

to evaluate the results of modified anterior lamellar keratoplasty (MALK) in patients with end-stage of keratoconus

Setting:

Anterior lamellar keratoplasty in keratokonus

Methods:

In 12 patients (12 eyes) with progressive keratoconus stage IV according to the Amsler-Krumeich classification and corneal opacifications underwent  the MALK. The method consists in forming a lamellar cut of the cornea of 8.5 mm with the removal of the surface turbid layers in the form of a central corneal disc d=6 mm, followed by fixation of the graft d=8.0 mm in the formed peripheral pocket, which allows maximum flattening and reliable corneal scar

Results:

In all cases the engrafting was transparent. The preoperative Kave decreased from 69.3 ± 14.6D to 43.5 ± 18.9D, the average corneal astigmatism was 4.6 ± 1.7D. The corneal thickness increased from 324±84 to 589±103 mc. In 1 year after surgery, an increase of UCVA from 0.02 to 0.1 and BCVA 0.08 to 0.5 was noted. No any case with graft rejection, inflammatory complications, perforation or damage to the deep layers of the cornea noted

Conclusions:

The use of modified anterior lamellar keratoplasty in patients with IV of keratoconus allowed to reduce the refractive power of the cornea by 38% and ensured the optimal thickness of the cornea for subsequent correction. Due to the automatisation of the process, the absence of a “penetrating technique” and the Descemet membrane separation, the method is not associated with intraoperative complications
