Clinical Scorecard: Choosing the Right Refractive Procedure

At a Glance

Key Highlights

• Preoperative evaluation may include biometry, corneal topography or tomography, OCT, and tear film assessment.
• PRK may be considered for selected patients with relatively thin but suitable corneas or for whom a corneal flap is a concern; recovery is generally slower than with LASIK.
• SMILE is for eligible patients with nearsightedness, with or without astigmatism, within its approved correction range.
• RLE replaces the natural lens; ICL corrects vision without removing corneal tissue or the natural lens.
• No single procedure suits every patient; selection should account for anatomy, age, prescription, daily needs, risks, and expectations.

Guideline-Based Recommendations

Diagnosis

• Assess eye health and visual requirements before recommending refractive surgery.
• Use biometry to measure eye dimensions, including corneal curvature and anterior chamber depth; it is important for intraocular lens power calculations.
• Use corneal topography or tomography to assess corneal shape and thickness and identify signs of keratoconus or ectasia risk.
• Consider OCT to image structures including the retina and optic nerve, and assess tear quality, stability, and ocular surface health.

Management

• Match the procedure to the patient's prescription, age, corneal suitability, ocular health, anatomy, and visual needs.
• Review prescription stability and procedure-specific eligibility; SMILE does not correct every type of refractive error.
• Consider alternatives such as ICL or, in selected cases, RLE when corneal anatomy makes laser correction unsuitable.
• Discuss benefits, limitations, recovery, risks, and the possibility that glasses may still be needed for some activities.

Monitoring & Follow-up

• Assess and appropriately manage dry eye issues before surgery.
• Plan postoperative reviews; ICL requires continued monitoring after surgery.
• For PRK, account for the time needed for the corneal surface to heal and its generally slower recovery than LASIK.

Risks

• Removing too much corneal tissue during laser correction can increase the risk of corneal ectasia.
• Preoperative screening may identify concerns associated with persistent dryness, glare, halos, or poor visual recovery.
• RLE permanently removes the natural lens; its benefits and risks require careful consideration, particularly for younger patients.
• Hormonal changes during pregnancy or breastfeeding can temporarily affect vision; the article states SMILE is not suitable during these periods.

Patient & Prescribing Data

Potential candidates include adults with stable prescriptions and suitable eye anatomy. The article describes PRK for selected patients with relatively thin but suitable corneas; SMILE for eligible nearsightedness with or without astigmatism; RLE often for adults over 40 with near-focusing difficulty or other stated indications; and ICL often for adults aged 21–45 with stable moderate to high myopia and adequate anterior eye space.

Procedure choice depends on individual measurements and needs. PRK reshapes the cornea after removing its surface layer; SMILE removes a laser-formed lenticule through a small opening; RLE replaces the natural lens; ICL places a lens inside the eye while retaining the natural lens. Eligibility and approved correction ranges require clinical review.

Clinical Best Practices

• Review corneal measurements and ocular surface health before selecting a procedure.
• Consider how age-related changes and daily activities, including reading, night driving, screen work, and sports, affect treatment choice.
• Identify and address preoperative concerns or consider another procedure when appropriate.
• Discuss recovery expectations and the possibility of continued glasses use.
• Consider diagnostic equipment, the surgeon's experience with the technique, and planned postoperative reviews.
