LASIK (Laser-Assisted in Situ Keratomileusis)



LASIK (Laser-Assisted in Situ Keratomileusis) is a surgical procedure used to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Pre-operative and post-operative examinations are crucial components of the LASIK process to ensure patient suitability for surgery, prepare for the procedure, and monitor recovery afterward. 


Pre-Operative Examination:

  1. Patient History: The eye care professional will review the patient's medical history, including any past eye surgeries or conditions, current medications, and general health status.

  2. Comprehensive Eye Examination: This includes tests such as visual acuity measurement, refraction to determine the patient's eyeglass prescription, and assessment of eye health using techniques like slit lamp examination and dilated eye examination.

  3. Corneal Evaluation: Specialized tests are performed to evaluate the shape, thickness, and curvature of the cornea. This may involve techniques such as corneal topography and pachymetry.

  4. Tear Film Assessment: The quality and quantity of tears are evaluated to ensure adequate lubrication of the eyes, which is essential for successful LASIK surgery and post-operative comfort.

  5. Discussion of Expectations and Risks: The eye care professional will discuss the patient's expectations regarding LASIK surgery, as well as potential risks, benefits, and alternatives. Informed consent is obtained from the patient before proceeding with surgery.

  6. Preparation Instructions: Patients receive instructions on how to prepare for LASIK surgery, including guidelines for discontinuing contact lens wear, avoiding certain medications, and fasting before the procedure.



Post-Operative Examination:

  1. Immediate Post-Op Evaluation: After LASIK surgery, patients undergo a brief examination to assess their immediate visual acuity and eye comfort. The surgeon may also examine the cornea to ensure proper flap alignment and wound healing.

  2. Follow-Up Visits: Patients typically return for follow-up visits within the first few days after surgery, followed by additional visits over the following weeks and months. These visits allow the eye care professional to monitor the patient's healing progress, visual acuity, and overall satisfaction with the results.

  3. Visual Acuity and Refraction: Visual acuity is measured at each follow-up visit to track improvements in vision. Refraction may also be performed to fine-tune the patient's vision correction if needed.

  4. Corneal Healing and Stability: The cornea is closely monitored for signs of healing and stability. This may involve examining the corneal flap (if created during LASIK) and assessing corneal thickness and curvature.

  5. Management of Post-Op Complications: If any post-operative complications arise, such as dry eye symptoms or glare/halos, the eye care professional provides appropriate management and guidance to address these issues.

  6. Long-Term Monitoring: Even after successful LASIK surgery, patients are typically advised to continue periodic eye examinations to monitor their eye health and vision over time.


Pre-operative and post-operative examinations are essential components of the LASIK process, ensuring patient safety, optimal surgical outcomes, and long-term visual health. These examinations are tailored to each patient's individual needs and play a critical role in the overall success of LASIK surgery.
