Procedures represented in the evidence
Counts describe structured records in this catalogue, not the total body of published literature.
ICL
An artificial collamer lens is implanted behind the iris and in front of the natural crystalline lens; the natural lens is not replaced.
Source: U.S. Food and Drug Administration — P030016/S035Follow-up: 3 months–8 years
LASIK
An excimer laser reshapes corneal stromal tissue after a corneal flap is created; the flap is then repositioned.
Source: U.S. Food and Drug AdministrationFollow-up: 1 day–2 years
PRK
The corneal epithelium is removed to expose the stromal layer, which is then reshaped with an excimer laser.
Source: U.S. Food and Drug AdministrationFollow-up: 3 months–10 years
RLE
The natural crystalline lens is removed for refractive purposes and replaced with an intraocular lens.
Source: PubMed — PMID 26605356Follow-up: 1 months–7 years
SMILE
A femtosecond laser creates an intrastromal lenticule corresponding to the refractive correction, which is removed through a small opening incision.
Source: FDA Summary of Safety and Effectiveness Data — P150040Follow-up: 1 day–5 years
TransPRK
A no-touch surface-ablation technique in which an excimer laser removes both epithelium and stromal tissue in a single-step treatment.
Source: PubMed — PMID 40698097Follow-up: 3 months–1 year
