Laser eye surgery has revolutionized the field of ophthalmology, offering millions of individuals the opportunity to achieve clearer vision and reduce their dependence on glasses or contact lenses. While the majority of laser eye surgeries are successful, like any surgical procedure, they carry certain risks and potential complications. Understanding these risks is crucial for individuals considering laser eye surgery. In this article, we will explore the common risks and complications associated with laser eye surgery, factors that may increase the likelihood of adverse outcomes, and steps to minimize potential risks [1].

Dry Eye Syndrome- Dry eye syndrome is one of the most common side effects of laser eye surgery, particularly LASIK. The procedure can disrupt the normal tear film and reduce tear production, leading to symptoms such as dryness, irritation, and discomfort. Undercorrection or Overcorrection- In some cases, the desired refractive correction may not be achieved, resulting in residual refractive error (under correction) or overcorrection of vision.This may require additional procedures or enhancements to achieve the desired visual outcome [2].

Visual Disturbances- Visual disturbances such as glare, halos, starbursts, or double vision may occur, particularly at night or in low-light conditions.These symptoms are usually temporary but may persist in some cases. Flap Complications (LASIK): LASIK involves creating a thin flap on the surface of the cornea before reshaping the underlying tissue with a laser. Flap-related complications such as flap dislocation, wrinkles, or epithelial ingrowth may occur, leading to visual disturbances or discomfort [3].

Infection: Although rare, infection of the cornea (keratitis) can occur following laser eye surgery, particularly if proper postoperative hygiene measures are not followed. Prompt treatment with antibiotics is essential to prevent vision-threatening complications. Regression: Some patients may experience regression of the initial refractive correction over time, necessitating retreatment or enhancement procedures to maintain optimal vision [4].

Preexisting Eye Conditions: Patients with preexisting eye conditions such as dry eye syndrome, corneal dystrophy, or glaucoma may be at increased risk of complications following laser eye surgery. Corneal Thickness: Adequate corneal thickness is essential for the creation of a corneal flap in LASIK or for tissue removal in surface-based procedures such as PRK [5].

Refractive Stability: Patients with stable refractive errors for at least one year are generally considered better candidates for laser eye surgery, as changes in prescription can increase the risk of undercorrection or overcorrection. Age: While laser eye surgery can be performed on individuals of all ages, older patients may have a higher risk of complications due to changes in corneal physiology and healing capacity [6].

Comprehensive Eye Exam: A thorough preoperative evaluation, including corneal topography, wavefront analysis, and pupil size measurement, is essential for assessing candidacy and identifying any potential risk factors for complications. Patient Education: Patients should be informed about the potential risks and benefits of laser eye surgery and encouraged to ask questions and voice any concerns they may have before proceeding with the procedure. Informed Consent: Obtaining informed consent involves discussing the risks, benefits, and alternatives of laser eye surgery with the patient and ensuring they understand the potential outcomes and limitations of the procedure [7,8].

Choose a Qualified Surgeon: Selecting a board-certified ophthalmologist or refractive surgeon with extensive experience and a proven track record of successful outcomes can help minimize the risk of complications. Follow Postoperative Instructions: Strict adherence to postoperative care instructions, including the use of prescribed medications, eye drops, and protective eyewear, is essential for promoting healing and minimizing the risk of complications [9].

Attend Follow-Up Visits: Regular follow-up visits with the surgeon allow for ongoing monitoring of healing progress and early detection of any potential complications that may arise [10].


Laser eye surgery offers a safe and effective solution for correcting refractive errors and achieving clearer vision. While the vast majority of patients experience successful outcomes with minimal complications, it is essential to understand the potential risks and complications associated with the procedure. By undergoing a thorough preoperative evaluation, choosing a qualified surgeon, and following postoperative care instructions diligently, patients can minimize the risk of adverse outcomes and enjoy the benefits of improved vision and enhanced quality of life
