ABSTRACT

Objective: to describe the results of deep lamellar keratoplasty in the surgical treatment of keratoconus in the Corneal Service of "Ramón Pando Ferrer" Cuban Institute of Ophthalmology.
Methods: a prospective descriptive study of 7 eyes with moderate keratoconus who underwent predescemetic lamellar keratoplasty. The universe consisted of 7 eyes fom patients who met the criteria for deep lamellar keratoplasty surgery. The variables age, sex, degree of keratoconus, pre-and postoperative visual acuity, postoperative astigmatism, topographic keratometry and pachymetry after a week, a month and three months of the surgery. Data were analyzed by using absolute, relative, mean frequencies and standard deviations.
Results: the 18-36 year age group in males represented 42,9 % as the 40-50 years-old group in females. In the studied group, 57,2 % of patients had advanced keratoconus. On the third postoperative month, 71,4 % of patients had visual acuity ranging 0,1 to 0,3 and 5-10 postsurgical astigmatism diopters. Pachymetry observed in 85,6 % of patients was higher than 560 um. The average keratometric value in the strongest meridian was 59,43 preoperatively and 47,77 postoperatively. In the weakest meridian, average keratometry was 50,28 and postoperative average amounted to 40,01.
Conclusions: predescemetic lamellar keratoplasty is a surgical technique providing greater advantages if compared to penetrating keratoplasty.
