Fresh Corneal Lenticule Implantation and Autologous Serum - Case Report

Not Applicable

Active, not recruiting

• Conditions: Keratoconus; Keratoconus of Right Eye; Keratoconus, Unstable, Right Eye

• Registration Number: NCT04594512
• Lead Sponsor: Eye Hospital Pristina Kosovo

Brief Summary

The aim of our study is to investigate the feasibility and the effect of fresh lenticule implantation as allogenic graft that will be taken from myopic patients to implant in patients with keratoconus disease using VisuMax Femtosescond laser- Smile module surgery with primary objective to increase central corneal thickness and secondary to improve visual acuity and reduces K-values and to show the autologous serum drop improve the recovery of patients with mild dry eye in keratoconus disease.

Detailed Description

A 19-year-old female patient with keratoconus and chronic hydrops cornea referred to the cornea department of our clinic with thin cornea and hydrops in chronic stage and minimal dry eye symptoms. Minimum corneal pachymetry in the right eye was 378 µm as measured by optical coherence tomography(AS-OCT-Zeiss). Atlas corneal topography showed steep K-values 82.60 ax.37 and flat K 75.15 D ax 127 with -7.45 corneal astigmatism. Her best corrected visual acuity was 0.0.5 in right eye and 1.0 in the left eye. Slit lamp examination showed intense punctate epitheliopathy (Figure 1), tear film break-up time (TBUT) was measured as 7-8 sec and Schirmer test was 10 mm in right eye, and the other eye examinations were determined normally.
