Clear Lens Exchange
Using many of the same techniques we have perfected in cataract surgery, we are able to remove the eye's natural lens and replace it with an artificial lens which better suits the needs of the eye. If someone is farsighted they need more power in their lens. We can place it in the implant and make a significant difference in how they see the world, usually without glasses. The procedure takes only about 15 minutes and allows most people to significantly reduce their need for glasses.
Many people who are not good candidates for Lasik or other laser refractive surgery may well be good candidates for Clear Lens Exchange. Clear Lens Exchange (CLE) is usually recommended to patients over 45 who wear bifocals, since it replaces the natural lens with an artificial one that cannot “accommodate” (shift focus between distant and nearby objects). Three options are available to correct for this loss:
- Multifocal lens implants – sort of “bifocals for the brain,” multifocal lenses have several built-in correction levels which the brain chooses from for the clearest view of any given object.
- Monovision – the eyes are adjusted so that one focuses on distant objects and the other on nearby objects.
- Bifocal or multifocal glasses or contact lenses.
Blended Vision (Monovision)
Probably the most effective means used over the past ten years to achieve good vision throughout the day without the need for glasses is Monovision. Essentially one eye is corrected for distance and one eye for near. With glasses this is difficult but many people use Monovision with their contact lenses successfully although the percentage of success may be only 50% overall using contacts.
When combining monovision with Lasik, Cataract surgery or Clear Lens Exchange, the success rate goes up dramatically as does the benefit for the patients. For many people it is the first time they can remember being able to function without glasses for most tasks.
