To study and compare the visual outcome of the second laser in situ keratomileusis (LASIK) one month after flap complications during first LASIK attempt, against what is reported in LASIK after 3 and 6 months.
Retrospective case of series of 30 patients (30 eyes) who underwent second LASIK after flap complications (irregular, thin, button holed and incomplete flap). The second surgery was performed one month after the first refractive surgery attempt. Uncorrected Visual Acuity (UCVA), Best Corrected Visual Acuity (BCVA) outcomes were studied.
In thirty eyes (N=30), causes of aborted LASIK were identified as 18 incomplete flaps (60.0%), 10 irregular flaps (33.3%), and 2 button holed (6.6%). The mean age for surgery was 28.1 years, 25 right eyes (83.3%) and 5 left eyes (16.3%). The mean time for second LASIK was 49.03 days (range 29 - 70 days). For the first procedure Moria microkeratome (Moria-Surgical ®) was used in 11 patients (36.6%), 4 eyes (36.4) with 90µm flap and 7 eyes (63.6%) with 130µm flap. In 19 patients (63.3%) Hansatome microkeratome (Bausch + Lomb ®) was used, 18 eyes (94.7%) with 160µm flaps and just 1 eye (5.26%) with 130µm flap. The second LASIK was performed in all 30 eyes (100%) with Hansatome microkeratome (Bausch + Lomb ®). Twenty seven eyes (90%) had a 180µm final flap and 3 eyes with 160µm final flap. The mean flap depth for the first LASIK was 140µm and mean depth for second LASIK was 177µm. Best spectacle-corrected visual acuity prior first LASIK was 20 patients (66.6%=20/20), 4 patients (30%=20/15), 3 patients (10%=20/25) and 3 patients (10%=20/30). The final UCVA after the second LASIK was 17 patients (56.6%=20/20), 9 patients (30%=20/25), 2 patients (6.66%=20/30), 1 patient (3.33%=20/15) and 1 patient (3.33%=20/40).There was only one complication observed during the second LASIK, irregular flap in 1 eye (3.33%), but laser ablation was performed with a UCVA of 20/30.
A planned LASIK one month after flap complications resulted in satisfactory UCVA, comparable to procedures 3 or 6 months after the first LASIK.
