Purpose
To show that the corneal Q value changes from conical to ellipsoid after FML intrastromal Keratoplasty in corneal cross-linked patients with KCN.
Setting
Eye Hospital, Pristina, Kosovo
Methods
30 eyes of 15 patients diagnosed with KCN, aged between 18 and 28 years, with central corneal thickness ranging between 420 and 450 µm, who underwent bilateral corneal cross-linking (CXL) were included in the study. FML implants were placed in all eyes with SMILE surgery. Changes in corneal Q values were examined 1, 3, 6 months, and 1 year after implantation.
Results
Preoperative CDVA decreased from 0.86 ± 0.22 logMAR (range: 0.40 to 1.10 logMAR) to 0.47 ± 0.09 logMAR (range: 0.30) at 1 year postoperatively. to 0.52 logMAR) (P < 0.001) improvement. Preoperative CCT increased from 420 to 530 μm (P < .001). The preoperative Q value increased from −0.80 to −0.48 (P < .001).
Conclusions
Corneal Q value changes from conical to ellipsoid after FML intrastromal Keratoplasty in corneal cross-linked patients with keratoconus. It is a safe, economical, and reliable technique that increases visual acuity, corneal thickness, and regeneration of healthy keratocyte and stem cell-like cells.
