Many Lagos residents celebrate cataract surgery as a life-changing event that restores clarity and color. However, a common question at SpecSMART Eye Clinic Ikoyi is: Why do I still need glasses after my cataract is gone? The truth is, while surgery removes the cloudy lens, glasses often remain necessary due to biological and optical factors.
Cataract surgery significantly improves vision but usually doesn’t eliminate the need for glasses completely. Factors such as residual astigmatism, presbyopia, and healing variations mean most patients will still benefit from glasses or specialized lenses. Regular post-op assessments at SpecSMART help optimize your vision and ensure your long-term eye health.
Understanding Limitations of Cataract Surgery
The Standard Monofocal Lens
Most cataract surgeries at our clinics involve monofocal intraocular lenses (IOLs), which focus light at one distance—usually far vision. This makes driving and watching TV clear without glasses, but near tasks like reading still require reading glasses or progressives.
Residual Astigmatism
Some patients have irregular corneal shape (astigmatism) that correction during surgery (using toric IOLs) isn’t always perfect. Even minor residual astigmatism can cause glare and blurry vision at night, especially in Lagos’s bright streets.
Presbyopia
As we age, the eye’s natural muscles lose flexibility. Standard IOLs are fixed, so near vision tasks like reading or using your phone require glasses. Special lenses tailored for near work are available for those who want to minimize dependence.
Refractive Surprises and Healing Influences
The eye’s healing process can cause slight shifts in vision, known as refractive surprises. These are usually temporary and can be corrected with glasses during the healing period.
Enhancing Your Life with Glasses
Post-surgery glasses also provide protection against glare during night driving and exposure to blue and UV light. High-quality anti-reflective coatings and polarized lenses are recommended for Lagos’s sunny environment.
The Post-Op Protocol at SpecSMART
-
Wait 4–6 weeks post-surgery before updating your prescription to allow vision to stabilize.
-
Our checklist includes detailed refraction, slit-lamp examination, and eye pressure measurement.
-
Discuss with your optometrist whether bifocals, progressives, or single vision lenses best suit your lifestyle.
Conclusion
While cataract surgery is a major step toward clear vision, glasses often remain part of the long-term solution. At SpecSMART Eye Clinic Ikoyi , we tailor post-op care to refine your vision, helping you see the vibrant Lagos skyline in HD.
