Your eye surgeon will work very closely with you to determine your goals, so that you can be as satisfied as possible with your vision post-surgery. The protruding lens through the iris creates a central bulge, resulting in increased lens power. The Crystalens has increased add power to improve near vision. After having a monofocal lens implanted into your eye, you may still need glasses or bifocals after surgery. Multifocal lenses were created to improve upon the limitations of monofocal lenses and traditional cataract surgery.

Patients want to see as

Your needs are best determined by your daily activities and which type of vision is of foremost importance to complete those activities. And the contrast sensitivity may be less than the monofocal lens. Initial results have been quite favorable. These lenses are usually used to restore distance vision.

The causes of glare halos and

Whether this is a concern is up for debate. Donnenfeld said that the new generation of lenses is making an enormous impact on his patients.

These questions, and more, will help your surgeon work with you to determine the best lens possible for you. So it is important to warn patients that they may be wearing reading glasses. Patients with glaucoma, macular degeneration, corneal disease, or other conditions will need a specific type of lens. Patients would still need to wear glasses or bifocals to restore their close-up vision. Steinert suggested that expectations, and perfection, may always hover just over the horizon.

Donnenfeld noted that with the Crystalens, he counsels his patients to wear sunglasses. However, both preclinical and clinical testing will be needed to verify this. He said the challenge extends far beyond the lens itself. Each lens has its own set of benefits and limitations.

During the workshop, participants discussed a number of issues to consider beyond the traditional statistical measures of precision, reproducibility, validity, and responsiveness. Specifically, the ReStor platform is now available with an aspheric lens as well as a decreased add power to extend the near focal point. MonoFocal Intraocular Lens Monofocal lenses are used to restore vision for one area of focus.

Patients can rarely experience glare and halos from a smaller optic zone and irregular astigmatism related to optic flexure. They can help restore crisp, clear distance vision for astigmatic cataract patients. For some patients, this is a good trade, but for truck drivers or x-ray technicians who work in a dark environment, this may not be a good trade, he said. Moreover, consensus is lacking on a number of issues, such as time for testing and whether testing should be binocular or monocular or both. Donnenfeld also suggested that spending more chair time with the patient prior to surgery allows the surgeon to manage expectations.

The causes of glare, halos and loss of contrast sensitivity are not necessarily related to the lens but rather to what Dr. Patients want to see as well as possible, and most want to minimize their dependence on spectacles. And the way they do this is they have a flexible lens that pushes through a very stiff iris.
