Lamellar keratoplasty vs penetrating keratoplasty

Abstract

Introduction Keratoconus is a progressive, bilateral, asymmetric, noninflammatory process of stromal thickness,
in which the normal shape of the cornea is distorted and develops a cone-like deformation, which progressively
modifies and alters vision and makes it more and more blurred, with the appearance of a decrease in visual acuity due to increased myopia, regular or irregular astigmatism, and the development of corneal
opacities.

Objective: To carry out a systematic review of the literature in the period 2014-2018 on the efficacy of lamellar
keratoplasty versus penetrating keratoplasty in the surgical treatment of keratoconus.

Material and methods: A systematic review of the literature was carried out, which included meta-analyzes
with level of evidence type A, scientific search engines such as Elsevier, Scopus, Pubmed, Cochrane Library,
Scielo were used in the period 2014-2018, on the efficacy of lamellar keratoplasty versus penetrating technique
in the surgical treatment of keratoconus. Twenty-three articles, Meta-analyzes, systematic reviews and
clinical trials on the subject were included.

Results: 24 scientific articles published in the journals Elsevier, Scopus, Pubmed, Cochrane Library, Scielo in
the period 2014-2018 were reviewed. From the review carried out, the effectiveness of Lamellar Keratoplasty
and its potentialities in Ophthalmology could be determined.

Conclusions: According to the reviewed evidence, it is concluded that the lamellar keratoplasty technique
turns out to be more effective and with less endothelial rejection rate compared to penetrating keratoplasty
within the surgical treatment of keratoconus.
