Cataract surgery

Multifocal IOL

The intraocular lens used in conventional cataract surgery is called a "monofocal intraocular lens," which focuses on a single distance. The postoperative lens does not have the ability to adjust the focus, so it is necessary to use eyeglasses to adjust the focus at distances other than the one that has been adjusted.
In contrast, "multifocal IOLs" allow the eye to focus on multiple distances. While this eliminates the need to wear eyeglasses, the sharpness and quality of vision is somewhat inferior to that of a monofocal lens because light is dispersed to multiple locations. In addition, when viewing light in dark places, halos and glare may be felt, and it is said that it takes time to become accustomed to this type of vision.

We offer a large number of multifocal intraocular lenses.

Fee for Treatment of Patients’ Choice

This is a medical service that allows patients with social insurance to receive treatment that is not originally covered by insurance in combination with insurance treatment by paying an additional cost (Fee for Treatment of Patients’ Choice ).

Cataract surgery using multifocal intraocular lenses had been self-funded and not covered by insurance.
With a few exceptions, mixed treatment (combining insurance and self-funded treatment) was not allowed, so if a self-funded multifocal intraocular lens was selected, the patient had to pay the entire cost of the surgery itself, which was covered by insurance (except for those who had special insurance for advanced medical care).

However, as of April 2020, cataract surgery using multifocal intraocular lenses will be covered by Treatment of Patients’ Choice. As a result, patients will only have to pay the additional cost of the multifocal intraocular lens and the surgery itself will be covered by insurance.

Fee for Treatment of Patients’ Choice

We are certified as a medical institution to perform cataract surgery with multifocal intraocular lenses. Eligible patients will be given a detailed explanation at the time of consultation.
