The lens of your eye goes through many changes as you age. The two most notable changes are the loss of flexibility and a change in the chemical composition.
- When the lens of your eye loses flexibility, it is called presbyopia. This change can begin to occur after the age of 40 and it reduces your ability to see close up with clarity. You may need reading glasses to see clearly.
- The chemical composition change is referred to as cataracts. This happens when the protein in the lens of your eye begins to bunch together. When light passes through this protein, you may notice a yellow haze or tint to images.
Two Conditions, One Solution
There is a solution to both of these conditions through the use of a synthetic lens called an Intraocular Lens (IOL). The synthetic lens works just like a natural lens, but you can eliminate both cataracts and presbyopia from ever happening again.
Technological advances have produced a variety of IOLs which also help to correct refractive errors. We offer a wide variety of cataract surgery replacement lenses in our Greenville, South Carolina, office:
- Monofocal IOLs
- Multifocal IOLs
- Toric IOLs
- Accommodating IOLs
Take our Cataract Lifestyle Questionnaire if you know you have cataracts and are ready for treatment. Your answers on this questionnaire can help determine the right IOL for your unique needs.
The most traditional IOL is a monofocal IOL. Mono means one and focal means focus of the lens of an eye. This means that monofocal IOLs will only provide vision for one distance. This distance, or power, for the lens is calculated prior to surgery and is usually selected to give you good distance vision. When monofocal IOLs are used, the patient will still require glasses for reading and near vision.
Multifocal IOLs are referred to as Advanced Technology IOLs or presbyopia-correcting IOLs because they are designed with multiple focusing properties. This means the lens can focus near, far, and in between which can eliminate the need for reading glasses.
Toric IOLs are also considered Advanced Technology IOLs because they were designed for people suffering from astigmatism. These IOLs are perfect for people suffering from cataracts and astigmatism.
Astigmatism is when a cornea has an oblong shape rather than a round shape. This causes light to focus on multiple points on the retina which results in blurred vision. The Toric IOL is designed to offset the shape of the cornea so that light focuses on the retina and vision is clear.
Accommodating IOLs are Advanced Technology IOLs that are designed to work with the muscles of the eye to focus upon whatever distance is needed. These IOLs provide sharp vision for multiple distances.
Dr. Donelson will recommend the best IOL option for you according to your lifestyle, medical and eye health history, and after performing a comprehensive consultation. To learn more about IOL options in Greenville, South Carolina, please contact us to schedule a cataract consultation.
