Contact lenses have been a significant advancement in vision correction since they gained popularity in the mid-20th century. They offer an alternative to traditional eyeglasses, providing improved peripheral vision and convenience for those with active lifestyles. Over 3 million people in the UK wear contact lenses, reflecting their widespread acceptance and essential role in addressing vision problems such as myopia, hyperopia, astigmatism, and presbyopia.

However, contact lenses are not without risks. Improper use, poor hygiene, and prolonged wear can lead to complications such as eye infections, corneal ulcers, and dry eye syndrome. These issues highlight the importance of adhering to proper lens care and usage guidelines to minimise potential hazard. Despite their benefits, these safety concerns have spurred interest in alternative treatments that may offer a better safety profile.

Advancements in vision correction technology, such as laser eye surgery (LASIK), provide promising alternatives. LASIK, a laser-based surgery, reshapes the cornea to correct refractive errors, offering a permanent solution with a high success rate and minimal recovery time. This option has been shown to reduce the long-term risks associated with contact lens wear, presenting safer and more effective solutions for vision correction.

In this article, we discuss the complications that may occur with long-term contact lens use and the alternatives available to you.

Eye Damage

Although contact lenses effectively correct poor eyesight, they can also cause significant eye damage over time. One major concern is that they promote corneal degeneration. Decades of daily use may increase the likelihood of developing corneal diseases. The constant presence of contact lenses in the eye can cause microtrauma and interfere with the natural healing process of the corneal tissue, leading to long-term degenerative changes.

Additionally, contact lenses can compromise the eye’s natural barrier to infection. By reducing the cornea’s oxygen supply, lenses create an environment conducive to bacterial and fungal growth. This hypoxic condition can weaken the corneal epithelium, making it more susceptible to infections. The risk is particularly high if lenses are worn for extended periods, especially overnight, or if proper hygiene practices are not followed.

The increased risk of infection due to contact lens wear is a significant concern. Infections like microbial keratitis can cause severe pain, vision loss, and even blindness if not treated promptly. Therefore, while contact lenses offer a convenient solution for vision correction, their potential to cause eye damage underscores the importance of exploring safer alternatives and adhering to strict hygiene protocols to minimize risks.

Corneal Ulcers

The problems with contact lenses don’t stop at corneal degeneration and infections. Extended-wear contact lenses, in particular, are associated with a heightened incidence of corneal ulcers. These painful open sores on the cornea can lead to permanent blindness if not promptly and effectively treated. The continuous wear of lenses, especially overnight, increases the risk of developing these ulcers by creating an environment where harmful microorganisms can thrive.

Contact lenses also interfere with the performance of the meibomian glands, which are essential for oiling and lubricating the eye area. This interference can lead to meibomian gland dysfunction, resulting in inadequate tear production and dry eye syndrome. Dry eye syndrome is a frequent side effect of wearing contact lenses, characterized by a persistent sensation of dryness, irritation, and discomfort in the eyes.

Corneal ulcers are a serious complication requiring immediate medical attention to prevent long-term damage. Symptoms include severe pain, redness, blurred vision, and sensitivity to light. The urgency of treatment underscores the risks associated with extended wear of contact lenses. Therefore, while contact lenses are a convenient solution for vision correction, their potential to cause severe eye problems necessitates careful consideration of usage practices and alternatives.

Patient Satisfaction

When compared with spectacles, contact lenses may be more aesthetically pleasing, but many individuals struggle to tolerate their use. 51% of people who discontinued contact lens wear cited discomfort as the main issue. In comparison, 40% reported their eyes became too dry with long-term use. These discomforts can stem from various factors such as lens material, improper fit, or sensitivity to lens cleaning solutions.

A study of current contact lens users discovered that half of all people surveyed had experienced at least one complication from wearing them. These problems included:

• Eye infections
• Dry eyes
• Visual difficulties
• Inflammation of the eye area

Additionally, the high level of maintenance required for contact lenses can be challenging for those with busy lives. Poor lens hygiene or falling asleep while wearing lenses are both major risk factors for developing microbial keratitis, a severe eye infection. Microbial keratitis can cause intense pain, redness, and discharge, potentially leading to vision loss if untreated.

The Main Alternative

While considering the pros and cons of contact lenses, it’s essential to look at the alternative treatments available. Glasses remain an option, but in our image-conscious society, many people search for another solution.

Laser Eye Surgery

Laser eye surgery is the most realistic alternative. It is a hassle-free option and a one-time procedure—there are no daily maintenance issues and no ongoing care required. Over the past 20 years, laser eye surgery has proven to be a safe and effective procedure.

At Precision Vision London, 98.5% of patients are satisfied or very satisfied with the outcome of their surgery, with serious complication rates below 1% at leading clinics. 99% of our laser customers achieve 20/20 eyesight following surgery, and an increasing number of contact lens wearers are choosing it to correct their vision issues permanently.

Laser eye surgery works by reshaping the cornea to correct refractive errors such as myopia, hyperopia, and astigmatism. The procedure is quick, typically taking less than 30 minutes, and most patients experience significant vision improvement within 24 hours. Recovery time is minimal, and patients can usually return to normal activities within a few days.
