Refractive surgery is a group of procedures that change how the eye focuses light. Some methods reshape the cornea, and some add or replace a lens inside the eye. The goal is sharper vision with less reliance on glasses or contacts. Not every eye is a match, so screening tests come first.

Implantable contact lenses place a lens inside the eye without removing the natural lens. Refractive lens exchange replaces the natural lens with an artificial lens.
A stable prescription helps, along with healthy corneas and no active eye infection. Dry eye can affect comfort and healing, so testing for dryness is part of screening. Thin corneas or irregular cornea shape may rule out certain laser options. A surgeon reviews medical history, meds, and vision goals before recommending a procedure.
Healing time depends on the procedure, with PRK usually taking longer for clear vision. Dryness and glare can show up during recovery and improve over time. Follow-up visits check cornea healing and vision stability. Eye drops and rest help the eyes recover after surgery.
Possible side effects include dry eye, glare at night, halos, and undercorrection or overcorrection. Infection and corneal haze are less common but serious. A second procedure is sometimes needed to fine-tune vision. A surgeon explains risk based on exam results and prescription strength.
LASIK is one type of refractive surgery. PRK, SMILE, and lens-based procedures also fall under refractive surgery. The best match depends on cornea shape and vision needs.
Some options can help with near vision, like monovision LASIK or certain lens implants. Results vary, and reading glasses may still be needed for small print. A surgeon can explain realistic outcomes for near tasks.
Many people keep stable distance vision for years. Natural aging changes still happen, including presbyopia and cataracts later in life. A long-term plan depends on age and eye health.
Unstable prescriptions, certain cornea conditions, or severe dry eye can make surgery a poor fit. Some health conditions also raise risk. A screening exam is the safest way to know.
