Refractive Lens Exchange & Premium Lenses

Refractive Lens Exchange vs Cataract Surgery

Refractive Lens Exchange and cataract surgery are the same operation. In both, the natural lens is removed and an implant placed. The difference is why and when: cataract surgery treats a lens that has become cloudy and is covered by insurance; RLE replaces a clear lens to correct vision, usually for presbyopia or a high prescription, and is elective. A patient who has RLE will never need cataract surgery, because the lens that would have clouded is gone.

The same surgery

Both procedures use the same incisions, the same ultrasound removal of the lens, the same implants and the same recovery. A surgeon performing RLE is performing cataract surgery on a lens that has not yet clouded; the technique, the lens choices and the technology are the same. That is part of what makes RLE a well understood operation: it draws on the safety record of cataract surgery, though younger and highly nearsighted eyes carry a higher risk of retinal detachment.

What decides which you are having

If the lens is clouded enough to affect your vision, the operation is cataract surgery, and Medicare or medical insurance covers the surgical portion with a standard lens. If the lens is clear and the goal is to correct vision, the operation is RLE and it is elective. There is a gray zone: early lens changes that are not yet a visually significant cataract. In that situation the evaluation will tell you plainly whether your insurer would consider the surgery medical or elective, because it affects what you pay.

Cost and coverage

Cataract surgery with a monofocal lens is covered. Premium lenses, and laser assistance or intraoperative measurement where used, are additional costs in either case. RLE is quoted in full, in writing, and financing is available. A patient who has RLE at 52 pays for it electively and never pays for or undergoes cataract surgery; a patient who waits until a cataract forms at 70 has insurance cover the surgical portion but wears glasses for the intervening years.

Lens choices are the same

Monofocal, toric, multifocal, trifocal, extended depth of focus and Light Adjustable lenses are all available for either procedure. RLE patients, who are choosing surgery for vision rather than accepting it for a cataract, almost always choose a premium lens, and the evaluation is built around matching the lens to their goals.

Frequently Asked Questions

The technique is the same, but younger and highly nearsighted eyes carry a higher risk of retinal detachment, which your surgeon will review with you. An RLE lens is soft and clear, which if anything makes removal gentler than a dense cataract.

Yes. At that point the surgery may be classed as cataract surgery, with the surgical portion covered by insurance and the premium lens as an additional cost. The evaluation clarifies which applies.

No. The natural lens is gone and the implant cannot cloud. A membrane behind the implant can haze years later in some patients and is cleared with a quick office laser.
