Bilateral simultaneous myopic PRK as experienced by an ophthalmologist

Area of Science:

• Ophthalmology
• Surgical Technology

Background:

• Excimer laser photorefractive keratectomy (PRK) and phototherapeutic keratectomy (PTK) are established corneal surgical procedures.
• Contact lens intolerance, exacerbated by environmental factors like dust, is a common reason for seeking refractive surgery.
• Patient preference for managing refractive correction and surgical discomfort is a key consideration in practice.

Purpose of the Study:

• To evaluate the feasibility and patient acceptance of bilateral PRK.
• To understand patient motivations for choosing unilateral versus bilateral PRK.
• To assess the impact of bilateral PRK on managing contact lens intolerance.

Main Methods:

• Performing excimer laser PRK and PTK procedures since November 1991.
• Documenting the number of PRK procedures, including bilateral cases and the timing between procedures.
• Analyzing patient requests and reasons for choosing unilateral or bilateral surgery.

Main Results:

• By August 1992, 83 PRK procedures were performed, with 28 being bilateral.
• A significant number of patients opted for PRK due to contact lens intolerance in a dusty environment.
• Many patients preferred simultaneous bilateral surgery to avoid anisometropia and reduce overall discomfort.

Conclusions:

• Bilateral PRK, particularly when performed simultaneously, is a viable option for patients experiencing contact lens intolerance.
• Patient feedback indicates a strong preference for bilateral procedures when feasible, citing convenience and comfort.
• The practice evolved to routinely offer bilateral PRK based on patient demand and positive outcomes.
