The Ultimate Guide to Laser Eye Surgery: Everything You Need to Know

What Is Laser Eye Surgery? 

Laser eye surgery is a procedure designed to correct common refractive errors by reshaping the cornea with a precision laser. These errors include: 

By changing the shape of the cornea, laser eye surgery enables light entering the eye to focus correctly on the retina, restoring clearer vision without the need for glasses or contact lenses.

Who Is a Suitable Candidate for Laser Eye Surgery?

For severe dry eye or prescriptions outside of the above parameters, there are other vision correction treatments that may be suitable, such as ICL surgery.  

A thorough consultation and detailed eye examination are necessary to determine suitability. 

Different Types of Laser Eye Surgery 

There are several methods of laser vision correction. The most commonly performed procedures are LASIK, LASEK and SMILE. 

LASIK (Laser-Assisted in Situ Keratomileusis) 

This is the most frequently performed type of laser eye surgery. A thin flap is created in the surface of the cornea, the underlying tissue is reshaped with the laser, and the flap is then repositioned. Recovery is quick and most patients notice improved vision within 24 hours.

LASEK (Laser-Assisted Sub-Epithelial Keratectomy) 

LASEK is better suited for patients with thinner corneas or those unsuitable for LASIK. It involves loosening the outer layer of the cornea before applying the laser. Healing takes longer than LASIK, but results are comparable.

In some cases, laser eye procedures may be considered for individuals with prescription limits previously thought untreatable, depending on technological advances and clinical suitability.

Follow-up appointments are scheduled to monitor healing and check results. Most patients see a significant improvement in vision within a few days. 

Dry eyes can occur temporarily and are usually managed with lubricating drops. It is important to attend all follow-up appointments to ensure healing is progressing well and to address any concerns early. 

Benefits of Laser Eye Surgery 

Laser eye procedures can offer life-changing benefits for people with vision impairments, helping them return to daily activities with more freedom and clarity. Whether it's playing sport, driving, working, or simply reading the small print, the benefits of clearer, unaided vision are far-reaching. 

Laser eye surgery can also reduce the cost and inconvenience of purchasing new glasses or contact lenses year after year.

Risks and Potential Complications 

Although laser eye procedures are considered very safe, all surgery carries some risks. Possible side effects include: 

Serious complications are very uncommon, particularly in experienced hands. At OCL Vision, all procedures are performed by consultant-level ophthalmologists to ensure the highest standards of care. 

Some patients may require enhancement procedures if the desired level of correction is not fully achieved the first time. Your surgeon will discuss all possible risks and outcomes before proceeding. 

Laser Eye Surgery vs Other Vision Correction Options 

Laser treatment is not the only option for vision correction. Alternatives include: 

Implantable Contact Lenses (ICL) 

Suitable for patients with high prescriptions or thin corneas. A synthetic lens is implanted inside the eye without removing any tissue. Vision is often exceptionally sharp. 

Refractive Lens Exchange (RLE) 

More common for patients aged 50 and over. It involves replacing the eye’s natural lens with an artificial one, similar to cataract surgery. 

These alternatives may be recommended if laser treatment is unsuitable. 

Your consultant will assess your visual needs and eye health to recommend the most suitable procedure. 

Cost of Laser Eye Surgery 

Pricing can vary depending on the type of procedure your choose. At OCL Vision, prices are transparent and inclusive of your full treatment pathway, including consultation, surgery, follow-up care, and any necessary enhancements*. Finance options are available to make private treatment more accessible. 

While the upfront cost of laser surgery may seem high, many patients find it cost-effective over time, especially when considering the ongoing expense of glasses, contact lenses, and prescription sunglasses.
