Laser-assisted in situ keratomileusis or LASIK is now an effective alternative to wearing glasses or contact lenses. As someone who wears glasses, I was advised to consider LASIK years ago, but because of some unique issues, I preferred to stick with glasses.

However, today, LASIK laser eye surgery is the best-known and most commonly performed laser refractive surgery to correct vision problems. Here is what you need to know before considering this procedure.

What is laser eye surgery?

Surgery using lasers is a medical practice that corrects common vision problems such as near-sightedness, farsightedness, and astigmatism. With technological advancements, procedures like LASIK in Las Vegas, PRK, and SMILE offer practical solutions for those looking to improve their eyesight. Many people worldwide have benefited from these life-changing procedures, experiencing significant improvements in their vision and overall quality of life.

How laser eye surgery works

The cornea is reshaped during the surgery to allow light to focus correctly on the retina. This is usually done using a laser that precisely removes corneal tissue. The focus of the light on the retina is essential for sharp, clear vision.

Advances in laser technology have increased the accuracy and safety of these procedures, which can produce outstanding visual outcomes for patients. Understanding how your eyes work and how laser correction at Las Vegas Eye Insitute can improve vision is the first step towards making an informed decision about surgery.

Types of laser eye surgery


The most popular laser eye surgery is laser-assisted in situ keratomileusis or LASIK. It entails modifying the underlying tissue and creating a tiny flap in the cornea. LASIK offers a quick recovery time and less discomfort post-surgery, making it a popular choice among patients. The procedure generally takes about 15 minutes for both eyes, and most patients notice their eyesight nearly instantly improves following the procedure.


Photorefractive Keratectomy (PRK) does not require creating a corneal flap. Instead, the cornea’s outer layer is removed before reshaping the underlying tissue. PRK is frequently advised for individuals with thinner corneas or those involved in contact sports. While the recovery period for PRK is typically more extended than that of LASIK, the outcomes regarding vision improvement are similar, making it a viable option for many.


Small Incision Lenticule Extraction or SMILE is a recent technique involving a small incision to remove a lens-shaped corneal tissue. This minimally invasive procedure offers comparable outcomes to LASIK and PRK with potentially fewer side effects. SMILE’s newer technology allows for a more gentle correction process, resulting in less post-operative dryness and faster recovery times for some patients.

Benefits of laser eye surgery

Laser eye surgery can offer numerous benefits, including immediate improvement in vision, quick recovery time, and the possibility of doing away with the requirement for contact lenses or glasses.

According to the American Academy of Ophthalmology, the success rate of LASIK is around 96%, making it a convenient option. Patients often report higher satisfaction with their quality of life post-surgery, enjoying activities without the inconvenience of corrective lenses.

Risks and considerations

While the procedure is generally safe, there are risks such as dry eyes, glare, and overcorrections. It’s essential to have a thorough consultation with an eye care professional to discuss your risk factors and determine the most appropriate procedure for your needs.

Understanding both the benefits and potential risks helps make sure you are realistic about your aspirations and are prepared for the outcomes of the surgery.

Preparing for laser eye surgery

Preparation involves a comprehensive eye exam to determine your eligibility. In this examination, your ocular physician will assess the thickness and shape of your cornea, pupil size, and any other factors that may affect the surgery’s success. You may also be advised to stop wearing contact lenses for a period before the surgery to ensure your corneas are in their natural shape. Following your eye doctor’s instructions carefully will help achieve the best possible outcome.

Post-surgery care and recovery

Care after surgery is essential for a speedy recovery. Most patients experience improved vision within a few days, but it’s necessary to follow all post-operative instructions given by your surgeon.

This includes using prescribed eye drops to prevent infection, reduce inflammation, and avoid strenuous activities for a specified period. Proper post-surgery care ensures optimal healing and helps achieve the best possible results from your procedure.
