Femtosecond laser (FSL)-assisted mushroom configuration deep anterior lamellar keratoplasty (DALK) is reliable and reproducible, stated a recent noncomparative case series.

Femtosecond laser (FSL)-assisted mushroom configuration deep anterior lamellar keratoplasty (DALK) is reliable and reproducible, stated a recent noncomparative case series.

A research group led by Dr R. Shehadeh-Mashor, Department of Ophthalmology, Toronto Western Hospital, University of Toronto, Canada, performed a noncomparative case series on 19 eyes of 19 patients who had undergone FLS-assisted mushroom configuration DALK. Data was available for assessment at varying times between 1 month to a year postoperatively.

Preoperative BCVA was 20/108 and at 3 and 13 months postoperatively the BCVA was 20/46 and 20/35, respectively. The most significant change in mean spherical equivalent was at 3 months and there was a 56% reduction in mean keratometric cylinder at 6 months.

The complications included three cases of small Descemet membrane perforation, three stromal rejections resolved with topical steroids and six cases of steroid-related IOP rise.

The procedure could mean earlier visual rehabilitation because of the mechanical stability and wound healing advantages of stepped corneal wounds.
