When Is the Right Time to Get Cataract Surgery?
Dr. Nikhil Nasta
2 min read
The old idea of waiting until a cataract is “ripe” is outdated for modern phacoemulsification. Today, the better question is: Is the cataract reducing your quality of life or safety enough that surgery’s benefits outweigh its risks for you?
Operate based on function - not only on Snellen numbers
Patients can have “acceptable” acuity in a dark clinic yet struggle with:
- Glare while night driving
- Contrast loss in rain, smoke, or dim restaurants
- Fine work (threading needles, recognising faces across a room)
- Profession-linked visual demands (designers, pilots, surgeons - case-specific)
If symptoms match your lifestyle, timing may be reasonable even if the chart still looks “okay.”
Reasons not to delay unnecessarily
Very dense (mature) cataracts can increase ultrasound energy, corneal swelling risk, and surgical complexity. That does not mean panic - but it does mean avoiding years of needless struggle can be sensible.
Medical timing (when surgery should wait or be staged)
Examples where your surgeon may optimise first:
- Uncontrolled inflammation/infection
- Active severe diabetic macular oedema needing treatment sequencing
- One-eye planning when the fellow eye still drives outcomes
Second-eye timing
Some patients operate on both eyes close together; others wait to confirm comfort and refractive target in eye one. There is no single universal rule - discuss binocularity and work needs.
