Abstract Details

Purpose:

Besides LASIK and SMILE, phototherapeutic keratectomy is currently being used increasingly for the treatment of myopia and myopic astigmatism. Due to the epithelial ablation and related defect in the ablation zone, PRK is characterized by a longer healing process and possible pain. After healing, comparable results can be found in the literature compared to the other above mentioned procedures. With transepithelial PRK, the epithelium is removed by the laser in one step, mechanical removal is not necessary with this new type of PRK.

Setting:

nordBLICK Augenklinik Bellevue

Methods:

We examined 74 eyes of 37 pat. retrospectively. Preoperatively, all patients were informed about possible pain and the longer duration of the healing process. Preoperatively, the eyes were cooled with BSS. After ablation, a sponge with NSAID eye dropes was placed on the cornea for 40 seconds to reduce inflammation and pain. Subsequently, a therapeutic contact lens was inserted for 5 days. The duration of the pain and pain level was documented in all patients. Visual acuity and refraction were measured in addition to anterior segment findings from the 2nd control onwards. Postoperatively medication was applied localy.

Results:

In more than 80% of the patients, pain observed within the first 36 hours. In all patients the epithelial healing was complete on the 5th postoperative day. The average uncorrected visual acuity on the first day was 0.5 (range 0.1-0.9) in the first week with monocular 0.8 (range 0.5-1.2) and binocular 1.0 (range 0.7-1.2). After 3 months, uncorrected visual acuity was 1.0 (range 0.7-1.2) and binocular 1.2 (range 1.0-1.5). Myopia decreased from -3.5dpt (range -0.5 - -7.5dpt) preoperatively to +0.2dpt (range -1.25 - +0.75dpt), astigmatism from -1.0dpt (range -2.75 - 0.0dpt) to -0.3dpt (range 0.0 - - -0.75dpt).

Conclusions:

transPRK is a very well accepted, safe and efficient method for the treatment of myopia and myopic astigmatism.
