Vision after MIGS usually improves steadily over several weeks. Exact timing depends on whether cataract surgery was performed at the same time and on individual healing.
Early visual changes
In the first days, swelling, stitches, and drops can blur sight. It is normal for vision to fluctuate slightly as the eye settles.
- Many patients notice useful improvement within one to two weeks.
- Glare or haloes may be more noticeable at first, especially after combined cataract surgery.
- Reading and driving may feel different while vision adjusts.
- Follow-up visits allow your surgeon to monitor healing closely.
- Glasses prescriptions are usually updated once the eye is stable.
Longer-term stability
Most people feel their vision has largely stabilised by six to twelve weeks. Any later changes are more likely due to glaucoma progression or lens adjustments.
- Persistent blur, distortion, or double vision should be assessed promptly.
- New glasses may further sharpen focus once swelling has resolved.
- Visual field tests track the impact of glaucoma over time.
- Good pressure control helps preserve long-term sight.
- Regular check-ups remain crucial even when vision seems stable.
