ASLA or PRK (Advanced Surface Laser Ablation or PhotoRefractive Keratectomy)
Both these procedures are still used widely, PRK was the “original” laser refractive procedure but advancements in Laser technology with fast flying spot lasers, and also improved methods of postoperative care, has allowed us to perform ASLA and with our third generation Solid State Laser, TEMLA. All are suitable for treating myopia or hypermetropia with astigmatism and have similar outcomes.
