Purpose
To evaluate the clinical efficacy and safety of double lenticule transplantation in keratoconus patients with chronic corneal hydrops.
Setting
Eye Hospital, Kosovo
Methods
This study included 24 keratoconus eyes with chronic corneal hydrops following prior corneal crosslinking, all of which were indicated for penetrating keratoplasty. The cohort consisted of 24 patients (mean age 21.2 ± 2.5 years; 13 males, 11 females). All underwent double lenticule transplantation with one full lenticule (134.2 ± 18.0 µm, −6.70 ± 0.91 D) and one semi-moon lenticule (149.4 ± 14.6 µm), customized to astigmatism. Lenticules were transplanted through an intrastromal pocket with 130 µm cap thickness. The target minimum postoperative central corneal thickness was 460 µm. All patients were followed for at least 12 months.
Results
At 1 year, UDVA and CDVA improved markedly (1.73 ± 0.24 to 0.76 ± 0.17 and 0.42 ± 0.07 logMAR). Q value improved (–0.75 ± 0.05 to –0.62 ± 0.04), keratometry decreased (K1/K2: 71.7/61.0 D to 66.8/61.0 D), and CCT increased (348.0 ± 20.3 to 482.5 ± 8.7 µm). No complications or rejection occurred.
Conclusions
Double lenticule transplantation using one full and one semi-moon lenticule is a safe and effective alternative to penetrating keratoplasty, providing stromal thickening, maintaining corneal clarity, and improving visual acuity in keratoconus eyes with chronic hydrops.
