LASIK Surgery: What to Expect Before and During the Procedure
Overview
Discover what occurs in the lead-up to and during LASIK surgery, a popular procedure for correcting vision.Pre-Surgery Preparation
For those wearing contact lenses, preparation is key:
- Soft Contact Lenses: Patients should stop wearing them 7 to 10 days before surgery.
- Hard Contact Lenses: Cease usage at least six weeks prior, plus an additional six weeks for every three years you've worn them.
Eye Examination
Before surgery, a detailed examination of the cornea’s surface is conducted using a computer-controlled scanning device. This process, which involves low-power lasers, creates a topographic map of the cornea, identifying astigmatism and other irregularities.Treatment Planning
Using the gathered data, the surgeon calculates the precise amount and location of corneal tissue to be removed. Patients are typically prescribed an antibiotic beforehand to minimize infection risks.Higher-Order Aberrations
These are complex visual issues not always detected in standard eye exams. Though often minimal in healthy eyes, refractive surgeries can sometimes induce higher-order aberrations, challenging traditional corrective measures like glasses or contacts.
Significant advances in LASIK techniques have reduced these risks substantially. While spherical aberration remains a concern, especially for large corrections, innovative solutions like "wavefront optimized" LASIK are addressing these challenges. Most patients report satisfaction even with conventional procedures.
Potential Complications
Though rare, some complications may occur:
- Flap Complications: The risk is about 0.244%. Issues like displaced or folded flaps may require repositioning but seldom result in permanent vision loss. Risks decrease with experienced surgeons.
- Slipped Flap: This is a frequent concern immediately after surgery, which is why rest and sleep are recommended to aid healing.
- Flap Interface Particles: While their significance is unclear, a Finnish study noted their presence in a significant percentage of eyes examined.
In conclusion, LASIK surgery is generally safe and effective, with most patients experiencing improved vision and high satisfaction. Proper preparation and choosing an experienced surgeon can further minimize risks and enhance outcomes.
