IOLs (intraocular lenses) are most often used to replace the crystalline lens during cataract surgery. A monofocal IOL corrects vision at one distance, and the patient continues to wear glasses to achieve either close or distant focus. Monofocal IOLs can also be used to achieve monovision, a solution for presbyopia. At Ophthalmology Physicians and Surgeons in Philadelphia, PA, we can explain your options and help you determine if a monofocal IOL is right for you.
Who Is a Candidate for Monofocal IOLs?
If you want to undergo monovision treatment, or if you do not mind wearing glasses after cataract surgery, monofocal IOLs may be right for you. Patients considering monofocal IOLs should be in good overall health and should have adequate corneal thickness. In addition, qualifying individuals will have healthy eyes that are free from infection and disease. During an initial consultation at our practice, your doctor will perform a thorough assessment to determine if this treatment is right for you.
Most patients choose to correct distance vision and then simply wear glasses for reading and other up- close tasks.
Monofocal IOLs are not for everyone. This treatment may not be the best option if you:
- Have chronic dry eyes
- Suffer from severe corneal scarring
- Have hepatitis C or diabetes
- Are pregnant
- Take certain medications
How Do They Work?
Most commonly, monofocal IOLs are used to replace a crystalline lens clouded by cataracts to re-establish clear vision and provide focus at one distance. This means that patients who choose this option will still need glasses. Most patients choose to correct distance vision and then simply wear glasses for reading and other up close tasks.
Presbyopia (age-related farsightedness) often begins affecting patients after age 40. One solution to this condition is monovision, in which one eye is attuned to close focus and the other is attuned to distant focus. The brain has the ability to adjust between the two and achieve more comprehensive focus. This can be achieved with contact lenses or monofocal IOLs. We recommend trying monovision with removable contact lenses before moving forward with a surgical procedure.
What to Expect during the Procedure
Generally, the surgical placement of monofocal IOLs takes about one hour in our office. It consists of three primary steps:
- Anesthesia: In most cases, IOL placement can be performed under local anesthesia. This involves the use of numbing eye drops, although injections may also be administered in some instances. Patients who are prone to severe anxiety may wish to consider general anesthesia.
- Removal of the crystalline lens: Once you are comfortable, your doctor will remove the crystalline lens. This may be completed using a number of techniques, including phacoemulsification, laser-assisted surgery, or removal through a small incision.
- IOL placement: After the natural lens has been removed, the monofocal IOL will be placed. In most cases, your doctor will fold the IOL to insert it through the incision. Once inside the eye, the lens opens to its proper position.
Following monofocal IOL placement, most patients can resume routine activities within 24 hours. To monitor your progress and assess your healing, the surgeon will see you for a follow-up the day after your procedure.
