Purpose
Our study aims to investigate the feasibility and effect of intrastromal fresh lenticule keratoplasty (Sutureless keratoplasty) as an allogeneic graft. To implant in keratoconus patients taken from myopic patients using VisuMax Femtosecond laser-Smile module surgery. Also, the primary aim is to increase the central corneal thickness and secondarily to improve visual acuity by changing the corneal shape (Q value) from conical to ellipsoid form.
Setting
Eye Hospital,Kosovo
Methods
All the patients were clinically diagnosed with progressive keratoconus. Forty eyes (twenty patients) underwent SMILE surgery (donor group), and forty eyes underwent sutureless keratoplasty with a smile module (recipient group). Visual acuity, corneal topography, and anterior segment optical coherence tomography were analyzed.
Results
Visual acuity, preoperative CDVA improvement from 1 ± 0 logMAR to 0.55 ± 0.09 logMAR ( P < 0.001). The preoperative K1 values decreased from 56.25 ± 0.94 D to 51.71 ± 0.68 D (P < .001), whereas K2 values decreased from 63.53 ± 1.40 D to 54.88 ± 0.96 D (P < .001).
The preoperative CCT increased from 338.35 ± 11.24 µm to 484.95 ± 5.00 µm (P < .001).
Conclusions
In this study both corneal central thickness and visual acuity improved by changing in corneal shape (Q Value) from conical form to ellipsoid. The efficacy and safety of FML intrastromal sutureless keratoplasty as a new surgical technique in patients indicated for penetrating keratoplasty were demonstrated based on this study's long-term follow-up results.
