The use of high-energy laser beam to treat anterior corneal pathology and smooth surface irregularities has gained wide acceptance in the field of ophtalmology in recent years. The purpose of excimer laser Phototerapeutic Keratectomy (PTK) is to ablate the superficial corneal tissue in a controlled manner via laser-tissue photochemical interactions. The advantages of excimer laser PTK in the treatment of corneal pathology includes; ablation of corneal tissue with precision and minimal thermal damage to the surroundings, allowing the surgeon to control carefully the depth and diameter of treatment thus resulting in a smooth template provided for re-epitelialisation. The value of the procedure, besides its potential to provide better visual results, lies in its ability to postpone or eliminate the need for lamellar or penetran keratoplasty and to increase the contact lens tolerance. Despite the great potential usefulness and the precision of excimer laser in the treatment of anterior corneal pathologies, PTK should be viewed as an adjunctive procedure to more conservative measures and its limitations must be understood carefully.Keywords: Excimer laser, Anterior corneal pathologies,
