Premium Cataract Surgery and the Lens Choices Behind It

Standard versus premium: the difference is the goal

Every cataract operation removes the cloudy lens and replaces it with a clear one. A standard operation uses a monofocal lens, usually set for distance, and most patients wear reading glasses afterward, and distance glasses too if they have astigmatism. A premium operation sets a further goal: to leave you as free of glasses as your eyes allow. It reaches that goal with a different lens and, where available and appropriate, with laser assistance, intraoperative measurement or image guidance to place that lens exactly where the calculations assumed.

The lens choices

• Toric lens: corrects astigmatism, so distance vision is clear without glasses; reading glasses are still needed. A widely used option
• Multifocal lens: distributes light between distance and near, giving useful vision at both for most everyday tasks; some patients notice halos at night while adapting
• Extended depth of focus lens: a continuous range from distance through intermediate, with fewer night symptoms than a multifocal; light readers are used for small print
• Light Adjustable Lens: a monofocal or blended result fine tuned after surgery with light treatments, for the most accurate distance vision and for eyes that are hard to measure
• Blended vision: one eye set for distance and the other slightly nearer, with monofocal or EDOF lenses, for patients who prefer to avoid multifocal optics

How the choice is made

The evaluation measures the eye's length, the cornea's curvature and astigmatism, the health of the retina and the tear film, and it asks how you use your eyes: driving at night, reading, screens, hobbies. Not every eye suits every lens. Significant dry eye, macular disease or an irregular cornea argue against multifocal optics, for example, and previous LASIK or RK argues for the Light Adjustable Lens. Your surgeon recommends the combination your eyes and your day support, and explains what each option would and would not do for you.

Realistic expectations

Premium lenses reduce the need for glasses; they do not promise a life without them. Most patients with a multifocal or EDOF lens do their daily activities unaided and keep light readers for fine print in dim light. Most toric patients need readers. Night halos with multifocal lenses usually fade as the brain adapts over weeks to months. Results vary from patient to patient, and the evaluation is where your own likely result is discussed plainly.

Cost

Medicare and medical insurance cover cataract surgery with a standard monofocal lens. The premium lens, and any laser step or intraoperative measurement used with it, are additional costs that insurance does not cover. They are quoted in writing before surgery, and 0% interest financing for up to 24 months is available, depending on treatment cost.
