Long-Term Contact Lens Use: Risks and Laser Treatment Eligibility - Ophthalmology

More Info

---

Long-term use of contact lenses, especially when worn continuously, can pose several risks to eye health. While your boyfriend may not currently experience discomfort or dryness, it is essential to understand that the absence of symptoms does not necessarily indicate that there are no underlying issues. Continuous wear of contact lenses, particularly overnight, can lead to complications such as corneal hypoxia (lack of oxygen to the cornea), increased risk of infections, and potential damage to the corneal epithelium.

The cornea requires a constant supply of oxygen, which is primarily obtained from the air. When contact lenses are worn for extended periods, especially during sleep, the lenses can block oxygen from reaching the cornea, leading to conditions like corneal swelling, neovascularization (growth of new blood vessels into the cornea), and even corneal ulcers. These complications can be serious and may result in permanent vision impairment if not addressed promptly.

Regarding laser treatment eligibility, such as LASIK, several factors must be considered. First, the health of the cornea is crucial. If your boyfriend has been wearing contact lenses for an extended period, an eye examination is necessary to assess the corneal condition. The cornea should be healthy and free from any signs of damage or disease before considering laser surgery. If there are any signs of corneal thinning, irregularities, or other complications due to long-term contact lens wear, LASIK may not be a suitable option.

Additionally, it is recommended that contact lens wearers discontinue their use for a specified period before undergoing LASIK. This allows the cornea to return to its natural shape and health, which is essential for accurate measurements and successful outcomes of the surgery. The typical recommendation is to stop wearing soft contact lenses for at least two weeks and rigid gas permeable lenses for at least three weeks prior to the evaluation for LASIK.

If your boyfriend is considering LASIK, he should consult with an ophthalmologist who specializes in refractive surgery. The doctor will perform a comprehensive eye examination, including corneal topography and pachymetry, to determine if he is a suitable candidate for the procedure. The doctor will also discuss the potential risks and benefits of LASIK, considering his long-term contact lens use.

In summary, while your boyfriend may not currently experience discomfort from wearing contact lenses continuously, it is crucial to recognize the potential risks associated with this practice. Long-term contact lens wear can lead to significant eye health issues, which may affect eligibility for laser treatment. A thorough evaluation by an eye care professional is essential to ensure the safety and health of his eyes before considering any surgical options. It is also advisable for him to adopt healthier contact lens habits, such as removing them before sleeping and following proper hygiene practices, to minimize risks and maintain optimal eye health.
