When is LASIK surgery not advisable for the patient?
LASIK surgery is not advised to a patient if they have any of the following:
- An eye disease that can cause the cornea to become thin and bulge out.
- A fairly good overall vision
- Severe nearsightedness
- Large pupils and thin cornea
- Age-related eye changes that cause vision to become dim
- Participation in contact sports where they can get a direct blow to the face
In all these situations, the eye specialist will recommend an alternative treatment method to correct vision problems.
How to prepare for LASIK Eye Surgery?
If you are an eligible candidate for LASIK surgery, the eye specialist will advise you to follow the tips below and to take some precautions to ensure that there are no complications during the procedure and your eyes respond well to the treatment. These tips include:
- Build a habit of drinking plenty of water to keep the body hydrated and improve your body’s healing abilities.
- Stop wearing the contact lenses before having LASIK. If you wear soft contacts, you’ll have to stop at least a week before the surgery. And if you wear hard contacts, you will have to stop wearing them at least a month before the procedure.
- This is important because wearing contact lenses can alter the shape of the cornea and affect the results.
- Wear loose and comfortable clothes as you’ll be undergoing surgery in those same clothes. It is important that you follow this advice and wear clothes that are appropriate to wear in the operating room as well.
- Ask your friend or family member to drive you back from the surgery center. Though you won’t be asleep during the procedure, the anesthesia will still have some lingering effects. Therefore, it is not safe for you to drive yourself.
- Avoid wearing any makeup, perfume, or lotions on the day of surgery as these products act like contaminants to the face.
- Do tell your surgeon about your medical history and any medication you are allergic to. This may impact the outcome of the surgery and the precautions you’ll have to take after surgery.
Benefits of LASIK Eye Treatment
LASIK treatment has become a popular way to restore clear vision in patients over the years. This is because it has many aspects that are beneficial for the patients. The key benefits of the LASIK eye treatment are:
- Improved Vision- The patient can achieve 20/20 vision or perfect eyesight after LASIK.
- Safety- The latest advancements and innovations in laser vision correction procedures make the surgery safer and more precise.
- Faster Healing- Being a minimally invasive surgery, LASIK has less downtime for the patient and the healing is also quick.
- Minimal Complications- There are very few complications of LASIK surgery and even those ones can be managed with certain medicines or precautionary steps.
- Less Expensive- Compared to the amount of money you spend on contact lenses, frames, and contact solutions over the years can easily make up for the expenses of LASIK surgery. And you’ll save more money when your vision is clear and you no longer need visual aids.
- Additional Adjustments- Another great benefit of LASIK is that if needed, you can undergo the procedure again to adjust your vision further if it changes.
Due to all these advantages, people are becoming more inclined to LASIK and other latest forms of vision correction too.
What are the different types of LASIK surgery?
As there are different types of LASIK eye surgery available, patients often have a hard time determining which laser procedure is the best for the eyes. LASIK itself is a type of refractive surgery that is performed with the help of a laser. People have heard many names for LASIK, such as Femto LASIK, Contoura LASIK, Smile, etc.
- LASIK- It can help to treat myopia, hyperopia, astigmatism, and presbyopia. LASIK is one of the most popular refractive surgeries and comes under blade-less procedures as a laser is used to cut the corneal flap.
- PRK- Photorefractive Keratectomy was the first technique that involved using lasers to correct vision problems. It can help to treat myopia, astigmatism, and presbyopia but not hyperopia. The key difference between LASIK and PRK is that it is done by removing the outer layer of the cornea whereas, in LASIK, only a small flap is created and lifted to reshape the cornea.
- ASA- Advanced Surface Ablation is similar to PRK but uses Zeiss excimer laser to ablate the cornea and reshape it to provide clear vision. It can treat myopia, astigmatism, and presbyopia.
- LASEK- Laser-Assisted Subepithelial Keratomileusis is also similar to PRK. But unlike PRK where the flap is created and removed, in LASEK, the flap is created and pushed to the side of the cornea where it remains attached to the eye. After surgery, the flap is repositioned and a bandage contact lens is placed on the eye to keep the flap in place as it heals. It can be helpful to treat myopia, astigmatism, and presbyopia. But you should know that LASEK is not USFDA-approved.
- EPI-LASIK- Used for correction of myopia, astigmatism, and presbyopia, EPI-LASIK is another variation of PRK. The flap of the outer layer of the cornea is created with the help of a special tool called an epithelial separator. It is also not approved by USFDA.
- LBV- Laser Blended Vision is a technique that helps to correct presbyopia only. It treats the dominant eye for distant vision and the non-dominant eye for near vision. It is a US FDA-approved technique.
- SMILE- SMILE stands for small incision lenticule extraction which is a new blade-free technique that uses a femtosecond laser to create a lenticule shape in the corneal tissue. The lenticule size and shape are adjusted to correct the refractive error of the patient. It is not approved by the FDA for myopia of less than 1 Diopter and neither for astigmatism or hyperopia. Therefore, it can only be used to treat high myopia.
Other than these techniques, there are other laser-based procedures that can correct refractive errors and treat other eye disorders like cataracts, glaucoma, diabetic retinopathy, etc.
Recovery & Post-Surgery Care After LASIK
You should understand that undergoing LASIK surgery is not enough to get the desired results and correct all the vision problems effectively. The most crucial thing is the recovery period. In the first few days, your eyes will itch, feel gritty, burn, or become watery. Your vision may also take 24-48 hours to stabilize. And the corneal flap will take even longer to heal completely.
The complete recovery time after LASIK is around one month during which you’ll have to take many precautions and follow the doctor’s advice strictly. If you don’t follow the doctor’s instructions, there is a possibility that your final outcome of LASIK won’t be exactly what you hoped for.
Here are some common post-surgery care tips that will help you to recover quickly and get the best results from LASIK:
- Do not touch or rub your eyes as it can cause irritation.
- Apply eye drops as directed by the doctor for faster healing and to reduce side effects like dry eyes.
- Get the right eye protection device to keep dust, dirt, and even strong light away from the eyes.
- Try to avoid direct sunlight and artificial light as well. Stay in the soft and dim light that soothes your eyes.
- Avoid heavy exercises and all kinds of sports activities until your eyes heal properly.
- Avoid soap for the first few days completely and don’t take showers or hot tub baths as well.
- Give enough rest to your eyes and keep them away from the digital screen in the first week as much as possible.
- Avoid wearing makeup, cream, or any other products with chemicals, including face wash.
- Take follow-up with your eye doctor to monitor the eye’s recovery and to detect signs of potential complications
