Laser Eye Surgery: Risks for Soft Contact Lens Wearers - Ophthalmology

Laser eye surgery, particularly procedures like LASIK and SMILE, has become increasingly popular for correcting refractive errors such as myopia (nearsightedness). However, if you are a soft contact lens wearer, there are specific considerations and potential risks associated with undergoing laser eye surgery.

One of the primary concerns for individuals who wear soft contact lenses is the potential for corneal neovascularization, which is the growth of new blood vessels into the cornea. This condition can occur due to prolonged and improper use of contact lenses, particularly if they are worn overnight or for extended periods. If the cornea has significant neovascularization, it can complicate the surgical procedure, as excessive blood vessels can lead to bleeding during surgery, which may affect the outcome.

Moreover, individuals with a history of dry eye syndrome, which is common among contact lens wearers, may face additional risks. Laser procedures can exacerbate dry eye symptoms, as the surgery can temporarily disrupt the corneal nerves responsible for tear production. If you already have dry eyes, the risk of developing post-operative complications, such as corneal epithelial defects or delayed healing, increases. This is particularly concerning for those who have been diagnosed with dry eye syndrome, as their corneal epithelial cells may have a reduced healing capacity.

It is also essential to consider your age and the degree of refractive error. At around 600 degrees of myopia, you may be a suitable candidate for laser surgery, but age-related changes, such as presbyopia (the gradual loss of the eye's ability to focus on nearby objects), may also play a role in your decision. If you are nearing your forties, even if laser surgery corrects your myopia, you may still require reading glasses for near vision due to presbyopia.

Before proceeding with laser eye surgery, it is crucial to have a thorough pre-operative evaluation by an experienced ophthalmologist. This evaluation should include a comprehensive eye examination, assessment of your corneal health, and a discussion of your medical history, including any issues related to contact lens wear. Your doctor will evaluate the health of your cornea, the presence of any neovascularization, and your tear film quality to determine if you are a suitable candidate for the procedure.

If you are deemed a candidate for laser surgery, your doctor may recommend a period of discontinuing contact lens wear prior to the surgery. This allows your cornea to return to its natural shape and helps to ensure the best possible surgical outcome. The typical recommendation is to stop wearing soft contact lenses for at least two weeks before the evaluation and surgery, but this duration may vary based on individual circumstances.

In summary, while laser eye surgery can be a safe and effective option for correcting myopia, soft contact lens wearers must consider the potential risks and complications associated with the procedure. It is essential to consult with a qualified ophthalmologist who can provide personalized advice based on your specific situation, including your eye health, degree of refractive error, and any underlying conditions such as dry eye syndrome. By taking these factors into account, you can make an informed decision about whether laser eye surgery is the right choice for you.
