Purpose
To investigate Corneal Q value changes after Fresh myopic lenticular implantation in keratoconus with femtosecond laser-assisted small incision lenticule extraction (SMILE) surgery.
Setting
EYE HOSPITAL,KOSOVO
Methods
Fifty eyes with advanced keratoconus indicated for corneal transplantation were included in this study. Fresh myopic lenticular implants were placed according to corneal topography in all eyes through SMILE surgery. Lenticular implants were extracted from patients with myopic refractive errors of the cornea.
Results
All patients were followed for five years.No reaction, infection, epithelial defects, punctate keratitis, deep lamellar keratitis, or signs of allogeneic rejection were observed in any of the patients. Q value improved from − 0.82 ± 0.04 preoperatively to − 0.60± 0.05 five years postoperatively (p < 0.001). The pre-operative CDVA improved from 1 ± 0 logMAR to 0.55 ± 0.09 logMAR (P < .001). The preoperative CCT increased from 398 ± 13.29 µm to 481.10 ± 8.12 µm (P < .001).
Conclusions
The intrastromal lenticule implantation procedure was clinically effective in improving corneal shape (increasing Q value) and vision in patients with keratoconus. The addition of fresh myopic lenticule increased corneal thickness while transforming the cone into an ellipsoid shape.
