Standard Lenses
Lens Implants for Both Distance and Near Vision (Presbyopia-Correcting Lens Implant)
It is now possible for many individuals to greatly reduce the need for glasses. As age 40 to 50 we routinely notice the need for additional lenses or glasses to provide focusing at different distances. This is the condition of presbyopia that occurs as the natural lens ages and becomes less flexible.
Several lens implants are now available that can correct this problem. They are specifically designed to provide enhanced vision at multiple distances. Our doctors usually prefer the Crystalens (by Bausch and Lomb) or the ReStor (by Alcon) to achieve this goal. These lenses work well for many, but are not for everyone. Careful discussion and examination are needed to determine appropriate candidates for such a lens. These lenses are require additional measurements, skill and services and are more expensive than standard implants. The additional costs are usually not covered by insurance but financing is available.
Advantages
- Reduced need for glasses for many tasks
- Reading usually possible without glasses
- Generally increased satisfaction with overall vision reported by most patients
Limitations
- Do not function as well if significant astigmatism is present
- Some glasses usage may still be needed
- Require more exact refractive surgical endpoints than standard monofocal lenses
- May require subsequent surgical ”enhancement“ or ”fine-tuning“ to refine results
- More examination and followup needed
- Additional Cost
Astigmatism-Correcting Lens Implants (Toric Lens Implant)
Astigmatism is an optical abnormality usually occurring when the cornea is not spherical, but is somewhat more elliptical or football-shaped. This is conventionally treated by glasses or contact lenses but can now be corrected by special lens implants. The astigmatism is neutralized by the lens which is rotated precisely within the eye to align with the direction of the corneal curvature. This is highly effective at reducing astigmatism and therefore at improving vision after surgery, reducing the need for glasses.
Additional measurements and followup is required which are typically not covered by insurance.
Advantages
- Provides improved, often very excellent vision
- Reduced need for glasses for some activities
Limitations
- Only astigmatism of limited degree can be treated. Very high amounts may require additional procedures
- Glasses will still be required for some activities
- Additional measurements and examination is required
- Additional cost
Premium Lens Implants
Newer premium lens implants are now available for patients considering cataract surgery. These lenses, when combined with highly accurate advances in eye measurements, sophisticated calculations and accumulated surgical experience, provide the most precise results possible. Our goal is customize the solution to best meet your visual goals.
