A variety of lenses, IOLs (intraocular lenses), can be placed in the eye at the time of cataract surgery. When considering cataract surgery, it is important to visit someone like Dr. Parekh, who has expertise in the full range of lenses, giving you the most options. These include: conventional implants, astigmatism correcting (Toric) implants, bifocal/multifocal and accommodating lenses.
What implant lenses are available for Cataract patients?
In the last several years, new technology has given us the ability to eliminate the hassles of having to wear prescription eyeglasses after cataract surgery. Previously, there were very few choices, but now we can ‘custom fit’ your vision to your needs and preferences. This custom fitting is considered the refractive part of cataract surgery and is typically not covered by insurance.
This process starts with a conversation about what you want out of the surgery with your optometrist. You’ll continue this conversation with Dr. Parekh, and based on your goals, Dr. Parekh can use highly precise measurements and then a special type and power of lens implant to get you to your goal. On occasion, a follow up laser procedure (like LASIK) is used for fine tuning adjustments.
Before your visit with Dr. Parekh, you should starting thinking the various Zones of Vision.
- Zone 1 is Near Vision, about 12-20 inches from your eyes. This would include reading newsprint, sewing or looking at a map.
- Zone 2 is Intermediate Vision, about 2-4 feet from your eyes. This would include looking at your computer screen, cooking, cleaning or reading a price tag.
- Zone 3 is Distance Vision, beyond 4 feet from your eyes. This would include watching TV, driving, golfing, and other sporting activities.
Based on your needs, Dr. Parekh can customize your vision to match your needs and preferences using a variety of different lens implants.
