Lasik Eye Surgery in India

There are several variations of LASIK eye surgery, each with its own specific technique or technology. Here are some common types of LASIK:

• 1. Traditional LASIK: This is the previously mentioned LASIK treatment is used to generate a corneal flap and an excimer laser is used to reshape the cornea.
• 2. Bladeless LASIK: Also known as all-laser LASIK or blade-free LASIK, this treatment creates the corneal flap with a femtosecond laser rather than a microkeratome blade.
• 3. Wavefront-guided LASIK: Wavefront technology creates a detailed map of the eye, measuring its unique imperfections. Wavefront-guided LASIK aims to address higher-order aberrations and provide enhanced visual outcomes, particularly for individuals with complex vision issues.
• 4. Wavefront-optimised LASIK: Similar to wavefront-guided LASIK, this technique also uses wavefront technology. However, it primarily focuses on preserving the natural shape of the cornea while making corrections to the refractive errors. It aims to maintain the cornea's natural curvature, reducing the likelihood of post-operative complications and preserving the quality of vision.
• 5. Topography-guided LASIK: The information from the map is used to guide the laser in reshaping the cornea, addressing irregularities and providing a more precise correction.
• 6. PRK (Photorefractive Keratectomy): PRK is an alternative to LASIK, where the corneal epithelium (outermost layer) is removed and discarded before the excimer laser reshapes the cornea.

It's essential to consult with an experienced ophthalmologist or refractive surgeon to determine which type of LASIK is most appropriate for your specific vision needs and eye health. They can evaluate your candidacy and recommend the best procedure to achieve the desired visual correction.

Before undergoing LASIK eye surgery in India or any other location, a series of diagnostic tests and evaluations are typically conducted to determine the suitability of the procedure for an individual. These pre-operative assessments help identify any underlying eye conditions, measure the refractive errors, and ensure that the person meets the necessary criteria for LASIK. Here are some common tests and evaluations performed:

• 1. Comprehensive Eye Examination: This examination includes assessing the overall eye health, checking visual acuity, evaluating the shape and thickness of the cornea, and examining the retina and other structures of the eye.
• 2. Refraction Test: The patient stares through a phoropter as the doctor switches between lenses to determine the most correct prescription.
• 3. Corneal Topography: Corneal topography offers a thorough map of the shape and curvature of the cornea. It helps identify irregularities, astigmatism, or other corneal abnormalities that may impact the outcome of the LASIK procedure.
• 4. Pachymetry: Sufficient corneal thickness is necessary for LASIK to ensure safe and effective results.
• 5. Dilated Pupil Examination: This helps rule out any retinal or macular abnormalities.
• 6. Tear Film Evaluation: The quantity and quality of tears are assessed to determine if the patient has dry eye syndrome, which can affect the healing process after LASIK. Special dyes or tests, such as Schirmer's test or tear breakup time (TBUT), may be used.
• 7. Medical History Assessment: Certain conditions like unstable vision, autoimmune diseases, or pregnancy may affect LASIK candidacy.

These tests and evaluations help the ophthalmologist determine if LASIK is a suitable option for the individual and to plan the procedure accordingly. It's important to consult with a qualified eye care professional or refractive surgeon to undergo a thorough examination and receive personalised recommendations for LASIK surgery in India.

Here is a general overview:

• 1. Preparation: You'll be seated in a reclining chair or bed, and numbing eye drops will be provided to keep you comfortable throughout the operation. The surgeon will also clean the area around your eyes.
• 2. Corneal Flap Formation: The surgeon will build a thin corneal flap using either a microkeratome (a mechanical device) or a femtosecond laser. A suction ring is placed on your eye during the treatment if a microkeratome is employed. After that, the flap is gently pulled and folded back to reveal the underlying corneal tissue.
• 3. Corneal Reshaping: The laser used produces a cold ultraviolet light beam that destroys minuscule amounts of tissue while accurately reshaping the cornea based on your refractive defect. The laser works in accordance with the measurements and calculations produced during your pre-operative evaluations.
• 4. Postoperative Care: You will receive instructions on how to care for your eyes in the immediate postoperative period and during the subsequent recovery period.

Both eyes can often be treated in the same session, allowing for simultaneous recovery.

It's important to note that while the above steps provide a general outline of the LASIK procedure, specific techniques may vary depending on the surgeon, the type of LASIK being performed, and the equipment used.

Undergoing LASIK surgery in India offers several potential benefits:

• 1. Advanced Medical Facilities: These facilities often have the latest diagnostic tools, surgical equipment, and experienced ophthalmologists, ensuring high-quality care and precise surgical outcomes.
• 2. Skilled Surgeons: India attracts highly skilled and experienced ophthalmologists specialising in refractive surgery, including LASIK. You can find specialists with expertise in various types of LASIK techniques, allowing you to choose the best option for your specific needs.
• 3. Comprehensive Preoperative Evaluation: India's eye care centres typically conduct thorough preoperative evaluations to assess your eligibility for LASIK surgery. These evaluations include detailed eye examinations, precise measurements of your refractive errors, and screening for any underlying eye conditions.
• 4. Range of Options: India offers a wide range of LASIK surgery options, including traditional LASIK, bladeless LASIK, wavefront-guided LASIK, and more. The availability of different techniques allows surgeons to tailor the procedure to your unique vision needs, increasing the chances of achieving optimal visual outcomes.
• 5. Accessibility and Convenience: India is well-connected with international and domestic travel routes, making it easily accessible for patients seeking LASIK surgery. The city also has a wide range of accommodations to suit various budgets, allowing patients to plan their stay conveniently during the treatment and recovery period.

It's important to research and choose a reputable eye care centre or hospital in India, ensuring that the surgeons are qualified and experienced in performing LASIK procedures.

Some possible side effects and risks include:

• 1. Dry Eyes: Dry eye symptoms, such as dryness, itching, burning, and a gritty sensation, are common after LASIK.
• 2. Fluctuating Vision: It's normal to experience fluctuations in vision during the healing process after LASIK. This can result in periods of blurred vision or difficulty focusing. Most people achieve stable vision within a few weeks or months, but for a small percentage, visual fluctuations may persist.
• 3. Undercorrection or Overcorrection: The intended level of vision correction may not be accomplished in some situations, resulting in undercorrection (insufficient correction) or overcorrection (overcorrection of the refractive error). To resolve these difficulties, enhancement treatments or the use of corrective lenses may be required.
• 4. Regression: In some individuals, the vision may regress over time, and a mild degree of nearsightedness, farsightedness, or astigmatism may return.
• 5. Corneal Ectasia: In rare cases, LASIK can weaken the cornea, leading to a condition called corneal ectasia. Monitoring corneal thickness and following proper screening protocols can help minimise the risk of this complication.
• 6. Infection and Inflammation: Following post-operative care instructions, including proper eye hygiene and using prescribed eye drops, can help reduce these risks.
• 7. Complications with Flap: Although rare, complications related to the corneal flap creation can occur, such as flap dislocation, wrinkling, or epithelial ingrowth (growth of cells under the flap). These complications may require additional interventions or surgical management.

Doctors will provide you with personalised information based on your eye health, refractive error, and other individual factors, helping you make an informed decision about undergoing LASIK surgery.

The recovery process after LASIK surgery varies from person to person, but here is a general timeline and overview of what to expect:

• Immediately After Surgery:
1. - You may experience some discomfort, such as a scratchy or gritty sensation in the eyes.
2. - Your vision may be cloudy or fuzzy, and you may be light sensitive.
3. - It is common for your eyes to tear up or feel watery.
• The First Few Days:
1. - The discomfort and blurry vision typically improve within the first few days.
2. - To avoid infection, minimise inflammatory processes, and encourage healing, you may be given eye drops or drugs. Follow the directions given to you by your surgeon.
3. - Resting your eyes and avoiding strenuous activities, such as heavy exercise or rubbing your eyes, is advised.
• The First Week:
1. - Most people experience significant improvements in vision within the first week, although it can continue to fluctuate.
2. - You may be able to return to work or normal activities, depending on your individual healing process and the nature of your occupation.
3. - Dryness and mild discomfort may persist, and you should continue using prescribed eye drops as instructed.
• The First Month:
1. - Your vision should continue to stabilise and improve during this period.
2. - The dryness and discomfort should continue to decrease, but some people may still experience mild symptoms.
3. - It's important to follow your surgeon's advice regarding the use of eye protection, such as sunglasses, especially in bright or sunny environments.
• Long-Term Recovery:
1. - Your vision should attain its final level of stability after a few months.
2. - Any residual dryness or discomfort should be minimal, and the use of lubricating eye drops may be recommended as needed.

It's important to follow these instructions diligently and reach out to your surgeon if you experience severe or persistent symptoms, unusual side effects, or any concerns during the recovery period.

During the recovery process, avoid activities that could potentially irritate or injure the eyes, such as swimming, using hot tubs, or applying eye makeup. Adhering to good eye hygiene practices, such as avoiding rubbing your eyes and keeping them clean, can also aid in the healing process. Patience and proper care during the recovery period will help ensure the best possible outcome.
