Why Dry Eye Treatment is Critical Before Cataract Surgery

If you're considering cataract surgery, you may be surprised to learn that the health of your eye surface could be just as important as the surgical procedure itself. At Menassa Vision, we believe in a "clean the windscreen" approach—optimising your ocular surface before surgery to ensure the best possible visual outcome.

The cornea—the clear window at the front of your eye—provides approximately 70% of your eye's focusing power. When planning cataract surgery, we take precise measurements of your cornea to calculate the power of the artificial lens that will replace your cloudy cataract. These measurements are only accurate if your tear film is stable and your cornea is healthy.

Dry eye disease and related conditions like blepharitis can create an irregular tear film that fluctuates throughout the day. This means measurements taken on different occasions—or even at different times on the same day—may vary significantly. The result? A lens calculation that's based on unreliable data.

For patients choosing premium lenses such as multifocal or toric IOLs, accuracy is even more critical. These advanced lenses are designed to precise specifications; even small errors in calculation can lead to disappointing outcomes and residual dependence on glasses.

Ms. Menassa's dual expertise in cornea and cataract surgery means she never overlooks the ocular surface. Every patient considering cataract surgery undergoes thorough assessment of their tear film, meibomian glands, and corneal surface. If problems are identified, she implements a treatment plan to optimise the eye before surgery.

This might include preservative-free lubricants, treatment for meibomian gland dysfunction, management of blepharitis, or anti-inflammatory medications. Only when the ocular surface is healthy and stable do we proceed to final measurements and surgery.

The "clean the windscreen" philosophy is what sets specialist care apart from high-volume cataract surgery. It takes more time and attention, but it's the difference between good vision and excellent vision.
