Some problems associated with LASIK 

problems associated with LASIK

People have benefited from laser eye surgery, which has a high percentage of patient satisfaction. However, as with any surgical procedure, LASIK has the risk of complications. It is critical that you assess the advantages and dangers of surgery before proceeding.

Several issues connected with LASIK flap surgery include the following:

Irregular Astigmatism. 

This is due to the uneven curvature of the corneal surface. Additionally, irregular astigmatism may emerge as a result of laser correction that is not correctly focused on the eye or as a result of uneven healing. As a result, symptoms such as double vision (diplopia) or “ghost pictures” may occur. The eye may need re-treatment or augmentation surgery in certain instances.

Ingrowth of epithelial cells. 

This occurs following lasik surgery when cells from the outer layer of the cornea (epithelium) develop under the flap. Epithelial ingrowth is often self-limiting and produces no complications. However, in certain instances (between 1% and 2% of LASIK surgeries), pain and/or impaired vision may develop, necessitating further surgery to raise the flap and remove the epithelial cells.

Keratitis lamellar diffuse (DLK). 

This condition, dubbed “Sands of the Sahara,” is inflammation behind the LASIK flap that may be caused by a variety of factors. Following LASIK surgery, some degree of corneal irritation is expected. However, if left unchecked, like in DLK, it may obstruct recovery and result in eyesight loss. If DLK develops, it is often treated with antibiotics and topical steroids.¬†Click here to learn more about “Sands of the Sahara”.

Additionally, the flap may need to be removed and cleansed to remove inflammatory cells and avoid tissue injury. This is an extremely rare bulging of the eye’s surface that may develop if too much tissue is removed from the cornea during LASIK or if the cornea was already fragile prior to LASIK as determined by corneal topography mapping. Keratoconus occurs infrequently after LASIK without identified risk factors. 

Generally, enhancement laser surgery is not appropriate; instead, gas permeable contact lenses or corneal implants (Intacs) may be prescribed to stabilize the cornea, or a procedure called corneal collagen crosslinking may be done to reinforce the cornea.

Dry eyes after LASIK. 

Certain individuals who get LASIK report a reduction in tear production, which may result in eye pain and poor vision. According to the April 2006 edition of the American Journal of Ophthalmology, about half of all LASIK patients have some degree of transient dry eye syndrome.

Dry eye syndrome is often transient and may be adequately treated with lubricating eye drops or other methods.

Dry eye symptoms typically resolve until the eye heals completely, which might take up to six months. Individuals who already suffer from severe dry eye are often ruled out as LASIK candidates.

Significant under-, over-, or regression correction. Not everyone achieves 20/20 vision after LASIK eye surgery, and some or all activities may need contact lenses or spectacles in rare situations. If too much or too little corneal tissue is removed, or if your eye’s healing reaction is abnormal, your visual result will be less than optimum.

One probable reason for a less-than-perfect result is that your eyes did not react predictably to laser eye surgery. Another possibility is that your vision was excellent early after LASIK but gradually deteriorated owing to “over-healing.”

In most circumstances, when your surgeon determines that your residual refractive error is stable, a considerable under-correction or regression may be effectively addressed with further laser vision correction.

Infection of the eye

Infections are uncommon after LASIK. Due to the fact that the corneal flap functions as a natural bandage, eye infections are less common after LASIK than they are following flapless corneal refractive treatments like PRK. Nonetheless, it is critical to take medicated eye drops as advised after LASIK to prevent infection and to reduce inflammation while your eyes recover. learn more about flapless laser eye surgery at

How Frequently Do LASIK Complications Occur?

LASIK surgery’s safety and efficacy continue to improve as a result of more advanced technology, surgical competence, and careful patient selection.

Complications were more prevalent in the early years of LASIK, when studies conducted in the late 1990s suggested that up to 5% of patients receiving laser vision correction encountered some form of difficulty. Nowadays, this figure is less than 1% for major issues.

A 2009 global evaluation of LASIK found that over 95% of those who had the procedure between 1995 and 2003 were happy with the result.

The public’s faith in LASIK has increased in recent years as a result of the high success rate of LASIK surgery. Additionally, the US military has expanded its use of laser eye surgery to reduce soldiers’ dependency on corrective eyeglasses. Over 224,000 military members have had laser eyesight correction as of 2008. Since the technique was originally adopted in the military in 2000, more than 45 studies on the safety and efficacy of LASIK and other treatments have been undertaken.

The majority of LASIK patients have reported excellent results. The majority of military patients see 20/20 or better without corrective lenses after the operation, and the risk of problems has been very low. According to one research, throughout this eight-year period, just one in 112,500 individuals sought medical disability retirement owing to problems from laser vision repair.

Another research found that 100% of pilots and other aviation personnel from the United States Navy and Marine Corps who received bespoke (wavefront-guided) LASIK achieved 20/20 uncorrected vision after two weeks of surgery.

When asked one month following surgery about their satisfaction, 95% of these patients said that the treatment improved their effectiveness, and 100% stated that they would suggest it to other aviators. The 2008 ASCRS annual conference included a presentation of the study’s findings.

After LASIK, Eyewear

Though the objective of LASIK surgery is to minimize the need for glasses or contact lenses, some patients may benefit from wearing glasses (part-time or full-time) after the treatment.

For example, if you have recurrent dry eye issues after LASIK, having photochromic lenses in your spectacles might assist alleviate photophobia (light sensitivity) associated with dry eyes.

For patients with modest residual refractive error who do not need further surgery, using corrective spectacles for specialized visual activities such as night driving is a useful option.

If you need glasses after LASIK, go for lenses with an anti-reflective coating for the greatest vision and comfort.

Additionally, if you are above the age of 40, consider progressive lenses to improve both your reading and distance vision.
