Abstract Details
Purpose:
To report the outcome of Trans-PRK procedure for high myopia and thin corneas
Setting:
This procedure was performed at Lasik Centre Surabaya. The author and surgeons did not have any financial disclosure in this study.
Methods:
Twelve myopic patients with thin cornea ( <500 micron) were undergone Trans-PRK procedure in Lasik Center Surabaya Eye Clinic using Amaris 750s. The mean corneal thickness was 483.14 ±15.96 micron and the thinnest cornea was 449 micron. The highest spherical correction was -10.00 Diopter(D). After the excimer procedure, the Mytomicin C was applied on the corneal bed for 12 seconds continued by irrigating the cornea with 20 ml BSS. Bandage contact lenses were used to cover the cornea 7 days post operatively. Tobramycin and dexamethasone combination eye drops were given until 2 weeks.
Results:
Twenty-two eyes were performed Trans-PRK. The mean age of the patients was 23.05 + 6.12 year-old. Average spherical equivalent was S-3.81 Diopter. One day post operatively, the mean UCVA was 0.8, mean spherical equivalent S-0.20 D. There was corneal haze in 6 eyes. On day-7 post operatively, mean UCVA was 0.9 with spherical equivalent S-0.62 D. Corneal haze still could be found in 4 eyes, but the visual aquity were good and no pain reported. On day-30 the mean UCVA remain 0.9 and spherical equivalent was S-0.49 D. No corneal hazy was found in all patients after 30 days.
Conclusions:
Trans-PRK as a surface ablation LASIK procedure has a promising outcome to be performed in thin corneas. Although the subject of this study was not represent all population, this procedure could have be considered to help myopic with thin cornea patients.
