- Abstract
Purpose: We compared outcomes of deep anterior lamellar keratoplasty (DALK) and automated lamellar therapeutic keratoplasty (ALTK) in patients with keratoconus. Methods: Seventy eyes with keratoconus that underwent corneal transplantation using either DALK ( n = 40) or ALTK ( n = 30) were included in this retrospective study. DALK was performed with Anwar's big-bubble technique and ALTK using an ALTK system. Best-corrected visual acuity (BCVA), refractive results, and complications were analyzed. Results: Mean follow-up in the DALK (16.68 ± 3.36 months) and ALTK (15.27 ± 2.50 months) groups were similar ( p = 0.058). Mean final BCVA of patients in the DALK group was 0.31 ± 0.14 logarithm of the minimum angle of resolution (logMAR) and in the ALTK group 0.34 ± 0.15 logMAR, ( p = 0.492). Corresponding figures for final postoperative spherical equivalents were −3.45 ± 0.77 D and −4.19 ± 0.99 D, respectively ( p = 0.001). Final postoperative degree of astigmatism was similar in the two groups: DALK −4.28 ± 0.66 D; ALTK −4.50 ± 1.05 D ( p = 0.307). Conclusion: Final visual acuity outcomes were comparable for the DALK and ALTK groups. Thus, ALTK seem to be as efficacious as DALK for surgical treatment of keratoconus.
