Cataract surgery and lens replacement surgery both involve removing the eye’s natural lens and inserting an artificial one. The main difference lies in timing and the reason for surgery.
When each is performed
Cataract surgery treats a cloudy lens that already affects vision and daily life. Lens replacement, or refractive lens exchange, is done earlier mainly to reduce dependence on glasses or contacts.
- Cataract operations are usually supported by national health services or insurers
- Lens replacement is often elective and self-funded
- Both use similar techniques and lens implants
- Suitability depends on age, prescription, and other eye conditions
Visual goals and risks
Both procedures can offer excellent vision, including options for multifocal or toric lenses. Risks and recovery are also similar.
- Lens replacement removes future cataract risk but carries the same surgical risks
- Multifocal lenses may reduce glasses use but can cause halos or glare
- Thorough pre-operative assessment checks retina and corneal health
- Discuss lifestyle, driving, and reading needs when choosing lens type
