Cataract surgery is a common and effective way to restore clear vision by replacing your cloudy natural lens with a new, artificial one. We spoke to Mr Vincent Dubois, a consultant ophthalmologist specialising in cataract and lens replacement surgery, to help us understand the various types of lenses available and how they can improve your vision.
Understanding cataract surgery and lens replacement
During cataract surgery, the cloudy lens inside your eye, which is known as a cataract, is removed and replaced with a clear, plastic lens. This lens comes in various shapes and sizes, and choosing the right one can make a significant difference in your vision and lifestyle.
Types of lenses available
- Standard lenses: Standard lenses are typically used in cataract surgery and aim to correct basic vision needs. If you previously wore glasses, your surgeon can choose a lens that matches your prescription, reducing the need for glasses after surgery. However, many people prefer to reduce their dependence on glasses, which is where premium lenses come into play.
- Astigmatism-correcting lenses: If you have astigmatism, a condition where the cornea (the front of the eye) is irregularly shaped, you’ll need a special type of lens to improve your vision. Astigmatism-correcting lenses, also known as toric lenses, are designed to address this issue. They contain two different powers to correct the irregular shape of your cornea, helping you achieve clearer vision without the need for additional corrective glasses.
- Driving and dashboard lenses: For those who want to improve their vision for activities like driving, a lens designed for distance and intermediate vision might be the ideal choice. Often referred to as a “driving and dashboard” lens, this type of implant helps you see clearly through your car windscreen and read the dashboard without glasses. However, for reading or other close-up tasks, you may still need reading glasses.
- Multifocal lenses: Multifocal lenses are a popular choice for those who wish to see well at all distances without relying on glasses. Much like bifocal or varifocal glasses, multifocal lenses have different zones for near, intermediate, and distance vision. These lenses can reduce or eliminate the need for glasses after surgery for around 90-95% of patients. Unlike bifocal glasses, which may require you to adjust your head position to see clearly, multifocal lenses provide a smoother transition between different vision ranges.
Choosing the right lens
Selecting the most suitable lens for your needs involves a detailed discussion with your ophthalmologist. Mr Dubois emphasises the importance of understanding your lifestyle and vision requirements to choose the best option. Factors such as your daily activities, visual goals, and whether you want to minimise your dependence on glasses will influence the choice of lens.
The decision-making process includes evaluating your current vision, discussing your preferences, and considering any additional visual needs you might have. Your ophthalmologist will guide you through the options, helping you make an informed choice that aligns with your expectations and lifestyle.
