16 Interesting Facts About Laser Vision Correction

Posted by  On 27-02-2024

Laser vision correction has come a long way since its inception, evolving into a safe and effective solution for individuals seeking freedom from glasses and contact lenses. With its fascinating history, technological innovations, and high success rates, laser vision correction continues to positively impact people globally, opening up new possibilities for clear and unencumbered vision.

Despite our familiarity with the remarkable capabilities of modern technology, certain aspects of laser eye surgery still manage to astonish people. Whether you’re considering laser vision correction or simply curious to learn more, explore the following facts:

1. The Revolutionary Excimer Laser Discovery

Laser vision correction owes its existence to the discovery of the excimer laser. This unique laser emits a cool ultraviolet light, making it ideal for precise tissue removal without causing heat damage. 

In 1983, Dr. Rangaswamy Srinivasan and his colleagues accidentally discovered the potential of the excimer laser in reshaping corneal tissue, laying the foundation for what would later become LASIK (Laser-Assisted In Situ Keratomileusis).

2. NASA’s Support for Excimer Laser Technology

Excimer laser technology gained momentum and support through research efforts funded by government agencies, including NASA. NASA was interested in excimer laser technology for potential space-based applications, such as materials processing and scientific experiments in microgravity environments.

3. LASIK’s Pioneering Role

Introduced in the 1990s, LASIK quickly became the most commonly performed laser vision correction procedure. It involves reshaping the cornea using an excimer laser, which allows for precise removal of corneal tissue to enable optimal light focus on the retina, thereby improving vision without needing glasses or contact lenses.

LASIK has been widely adopted and has undergone refinements over the years, becoming a popular choice for many individuals seeking to reduce their dependence on corrective eyewear.

4. Beyond Near- and Farsightedness

Laser vision correction, exemplified by procedures like LASIK and PRK (Photorefractive Keratectomy), transcends the conventional boundaries of addressing nearsightedness and farsightedness. 

It emerges as a versatile solution effectively correcting astigmatism—a condition marked by irregular corneal shape. These procedures reshape the cornea by leveraging the precision of the excimer laser, ensuring accurate light focus on the retina, thus broadening the scope of visual corrections.

5. Military and Astronauts’ Embrace of LASIK

LASIK’s swift adoption extended beyond the civilian population, finding favour among military personnel and astronauts. Recognizing its advantages, various armed forces, including branches of the U.S. military, embraced LASIK-treated eyes as fit for service. This endorsement highlighted the procedure’s efficacy in demanding and dynamic environments.

6. Laser Cooling Effect

An intriguing aspect of laser vision correction lies in the excimer laser’s unique “cool” property. This laser removes tissue without generating heat by operating in the ultraviolet range. 

This cooling effect is crucial during procedures like LASIK, preventing overheating of surrounding tissues. The precision and safety afforded by the cool laser make it an indispensable tool in achieving optimal vision outcomes.

7. Microns Matter

The excimer laser employed in laser vision correction, notably LASIK, boasts exceptional precision. With the capacity to eliminate tissue from the cornea in microns, where one micron is approximately 1/25,000th of an inch, this precision is paramount in reshaping the cornea. 

It enables the correction of refractive errors without inflicting substantial damage to the surrounding tissues. This capability to operate on such a minute scale significantly enhances the success and safety of laser vision correction procedures.

8. No More Reading Glasses?

Presbyopia, the gradual loss of eyes’ ability to focus on nearby objects, is a common concern as people age. While laser vision correction remains a powerful tool for improving distance vision, integrating multifocal or accommodating intraocular lenses caters to the nuanced visual needs associated with presbyopia. 

This dual-focus approach ensures a more comprehensive and adaptable visual outcome, enhancing the overall quality of life for individuals navigating the challenges of presbyopia. However, laser vision correction can improve distance vision but may not eliminate reading glasses. 

9. High Success Rates

Laser vision correction, particularly LASIK, is known for its high success rates. Many patients experience significant improvements in their vision, with the majority achieving 20/20 vision or better after the procedure. 

However, the level of success can depend on various factors, including the patient’s overall eye health, the severity of their refractive error, and the surgeon’s expertise in performing the procedure.

10. Speed and Minimal Downtime

LASIK surgery is known for its speed, efficiency, and minimal downtime. The laser treatment reshaping the corneas to correct refractive errors takes less than a minute per eye. 

The entire LASIK procedure, from the creation of the corneal flap to the laser ablation and repositioning of the flap, is usually completed in about 20 minutes or less. After the procedure, most patients can expect to recover in less than 48 hours and with virtually no discomfort.

11. Cost Considerations

The economic aspect of laser vision correction introduces a consideration of varied costs influenced by factors such as technology and geographic location. While the initial cost may appear substantial, many view laser vision correction as a long-term investment

This perspective is grounded compared to the upfront expenses against the ongoing costs associated with glasses or contact lenses, highlighting the potential cost-effectiveness over time.

12. No Need for Stitches

The doctor creates a corneal flap during LASIK surgery, usually with the help of a microkeratome or a femtosecond laser. The surgeon lifts this flap to expose the underlying corneal tissue for laser ablation. After the laser treatment, the surgeon repositions the corneal flap. The corneal tissue naturally tends to adhere, and the flap typically remains in place without stitches.

The absence of stitches contributes to a quicker recovery time and less discomfort for the patient. The cornea’s natural healing process, along with the adherence of the flap, helps stabilize the treated area.

13. Suitable for Younger Individuals

Laser vision correction isn’t for a specific age group; it can benefit individuals as young as 18, provided their vision prescription has stabilized. This early intervention offers long-term vision clarity, allowing young individuals to pursue personal and professional goals unencumbered by visual impairments.

14. Patient Satisfaction

A consistent theme in studies exploring laser vision correction is the remarkable level of patient satisfaction. The transformative impact on daily life and the convenience of a glasses-free lifestyle resonates strongly among those who undergo these procedures. 

Activities such as sports, outdoor pursuits, and routine tasks become not only more accessible but also more enjoyable, underlining the profound positive impact on patient satisfaction.

15. Technological Evolution in Laser Vision Correction

Continual technological advancements shape laser vision correction. From Custom Bladeless LASIK to ReLEx SMILE (Small Incision Lenticule Extraction), ongoing research aims to improve outcomes, expand eligibility, and address a range of visual impairments, ensuring safer, more effective, personalized solutions.

16. Limited Need for Second Procedures

Most individuals experience significant vision improvement after the initial laser vision correction surgery. Advances in technology and surgical techniques minimize the likelihood of retreatment, with only 10% requiring a second procedure. Decisions for a second intervention are on an individual basis after a thorough evaluation.
