Purpose

We aim to investigate patient satisfaction after intrastromal fresh myopic lenticular Keratoplasty with Smile module in patients with advanced keratoconus.

Setting

Eye Hospital,Pristina,Kosovo

Methods

44 eyes of 32 patients between the ages of 18 and 38 were diagnosed with Stage 2 or 3 advanced keratoconus according to the Amsler-Krumeich classification and for patients with minimum and maximum corneal thickness of 300 and 419 µm, fresh myopic lenticular intrastromal keratoplasty was performed with the smile module according to the corneal topography. The thick side of the myopic lenticule was placed on the thin side of the keratoconus. After intrastromal keratoplasty, the corneal thickness was targeted to be at least 460 µm.

Results

Patients were followed for 3 years. The preoperative CDVA improved from 1.49 ± 0.31 logMAR to 0.47 ± 0.06 logMAR (P < .001). The postoperative visual acuity increased compared to the preoperative acuity. Preoperative K1 values decreased from 58.25 ± 0.94 D to 52.71 ± 0.68 D (P < 0.001), while K2 values decreased from 69.53 ± 1.40 D to 55.88 ± 0. 96 D (P < 0.001). Also, the preoperative CCT increased from 336.35 ± 11.28 µm to 476.35 ± 4.21 µm (P < .001).

Conclusions

In patients with advanced keratoconus, when the thickness of the fresh lenticule is calculated and implanted depending on the corneal thickness, both the corneal thickness increases and the corneal shape (Q value) changes from conical to ellipsoid form and also increasing visual acuity.
