PEREZ PARRA, Zaadia et al. Visual results in patients operated of deep anterior lamellar keratoplasty versus penetrating keratoplasty in keratoconus. Rev Cubana Oftalmol [online]. 2020, vol.33, n.1 Epub 17-Jun-2020. ISSN 1561-3070.
Objective:
Compare the visual results of deep anterior lamellar keratoplasty versus penetrating keratoplasty in the surgical treatment of keratoconus.
Methods:
A longitudinal analytical prospective study was carried out in 81 patients with keratoconus, operated of penetrating keratoplasty and deep anterior lamellar keratoplasty between the years 2014 and 2018. The variables analyzed were the age, the sex, the corrected visual sharpness, the sphere, the cylinder and the spherical equivalent.
Results:
The average of age in operated patients of deep anterior lamellar keratoplasty was 27,5 ± 10,0 years, and 33,2 ± 12,9 years in operated of penetrating keratoplasty. In both groups the masculine sex predominated: 62,5 % in the group of deep anterior lamellar keratoplasty and 63,3 % in penetrating keratoplasty. The corrected visual sharpness in operated of queratoplastia lamelar previous deep was 0,8 ± 0,19; the refractive cylinder -3,50 ± 1,50; the spherical equivalent -6,07 ± 3,61, SimK1 of 46,37 ± 2,47 dioptres and SimK2, 43,05 ± 2,47 dioptres. In the penetrating keratoplasty, the corrected visual sharpness was 0,68 ± 0,19; the refractive cylinder -2,77 ± 0,98 dioptres; the spherical equivalent -3,68 ± 1,56 dioptres, SimK1 and SimK2 of 44,58 ± 2,77 dioptres and 41,40 ± 2,93 dioptres respectively.
Conclusions:
The refractive results are similar in both surgical technicians.
