The eye focuses with 2 main lens systems:
- The Cornea: the cornea has a curvature to it that allows sight to enter and focus onto the retina for clarity of vision. In some cases the cornea is shaped irregularly creating what is called an astigmatism (similar to looking at the back of a spoon).
- The Lens: The lens is a clear structure behind the color part of your eye (iris). It focuses light rays onto the back of the retina for clarity of vision.
What happens to the lens with age?
- Around 40 years of age, one begins to lose their near vision and worse each year that requires reading glasses to see up close.
- Around 50 years of age, the lens begins to lose its clarity slightly and one an begin seeing abnormally whether at night or during the daytime.
- Around 60 years of age and above, the lens can become cloudy and worsens with age causing a significant cataract that is affected vision and limiting one’s ability to perform their daily activities such as reading, watching TV, playing sports, driving during the daytime or at night.
How to correct one’s vision?
Depending on your vision goals and the whether the issue is with your cornea or lens, Dr. Melendez will evaluate the entire visual system to determine what is your best option to correct your vision.
With all of the latest technology, we can help you become less dependent upon glasses if that is your goal. If you do not mind wearing glasses, then Dr. Melendez recommends then staying with your glasses after the surgery, the difference of course would be that your vision will be clearer, sharper, more vibrant, and better contrast after the surgery.
Some individuals desire to get rid of their glasses and in most instances, this can now be achieved with newer laser technology that is more precise and predictable.
