Standard LASIK Procedure for Correcting Blurred Vision

LASIK is the most well-known and frequently performed laser refractive surgery designed to address vision issues. Laser-assisted in situ keratomileusis (LASIK) serves as an alternative to eyeglasses or contact lenses.

• The procedure employs a specialized cutting laser to reshape the cornea, enhancing vision.
• In a normal eye, the cornea refracts light precisely onto the retina. However, in cases of nearsightedness (myopia), farsightedness (hyperopia), or astigmatism, improper refraction results in blurred vision.
• While glasses or contact lenses can correct these issues, reshaping the cornea provides a permanent solution.

Why It's Done

Near Sightedness (Myopia)

If the eyeball is slightly elongated or if the cornea curves too steeply, light rays focus in front of the retina, causing blurred distant vision. Individuals with myopia can see nearby objects clearly but struggle with distant vision.

Risks

Though vision loss due to LASIK is rare, some temporary side effects, such as dry eyes and glare, are common. These issues usually resolve within a few weeks or months and are seldom long-term concerns.

Potential Risks of LASIK Surgery

Dry Eyes

LASIK can temporarily reduce tear production, leading to dry eyes during the healing process, typically lasting up to six months. Artificial tears may help, and in severe cases, tear duct plugs can be inserted to retain moisture.

Glare, Halos, and Double Vision

Post-surgery, patients may experience increased sensitivity to light, halos around bright sources, or double vision, particularly at night. These symptoms typically subside within a few days to weeks.

Under Corrections

If too little corneal tissue is removed, vision improvement may not be optimal. Nearsighted individuals are more prone to this issue and may require a follow-up LASIK procedure.

Overcorrections

In some cases, excessive tissue removal can occur, making overcorrections more challenging to rectify than under corrections.

Astigmatism

Irregular corneal tissue removal may cause astigmatism, which may require further surgery, contact lenses, or glasses for correction.

Flap Complications

Issues such as infection or excessive tearing can arise when the corneal flap is lifted or removed during surgery. In some cases, abnormal tissue growth beneath the flap may occur.

Regression

Some patients may experience a gradual return to their pre-surgery prescription, though this is less common.

Vision Loss or Changes

While rare, certain surgical complications can lead to vision loss or reduced clarity compared to pre-surgery vision.
