How does LASIK work?

LASIK came into operation in the early 90s. And, since, then it is has been the most used form of laser eye surgery today. LASIK is an acronym for laser-assisted in situ keratomileuses, the best-known laser refractive surgery that corrects vision problems.

The surgeon uses a laser to make a tiny flap across the patient’s cornea during the LASIK procedure. The surgeon then folds the flap and uses a second laser to reshape the cornea. This process automatically corrects the patient’s vision allowing the eyes to focus more clearly. 

You might have also noticed that it doesn’t take more time to perform the entire LASIK procedure. Depending on the surgeon’s experience, everything should last for more than 30 minutes. 

During LASIK, patients don’t feel any pain. The surgeon would have relaxed the patient’s nerves before the procedure started. Since the surgery is 100% blade-free, it goes easy. 

After LASIK, the flap does not heal on the spot. It takes a little time before your eyes get restored to a perfectly healthy state. As often recommended, patients should not engage in eye-straining activities such as driving, running, and watching mobile phone screens or television immediately after the surgery. However, you can continue to do all that after your eyes have been perfectly healed. The first phase of LASIK healing takes only 24 hours. But, you will have to wait for seven days before you can resume your daily hobbies and activities.

Meanwhile, LASIK may come with some side effects. Some of the most common issues patients experience after LASIK include dry eye symptoms and mild eye infection. 

LASIK is a reliable correction procedure for major eye problems such as near-sightedness, farsightedness, and astigmatism. 

How does SMILE works?

SMILE is the latest innovation after LASIK. This procedure tends to be minimally noiseless, odorless, and less invasive. Like LASIK, SMILE also provides a long-lasting solution to different levels of eye problems, whether mild or severe. It doesn’t take much time for surgeons to perform the whole procedure. 

During a SMILE eye surgery, the surgeon will remove a thin layer that looks very similar to a contact lens from the eye’s surface via a small opening. This layer sits beneath the eye. After removing the layer, the surgeon then reshapes the cornea to correct the refractive error. At the end of this process, the patient gets a better vision.

SMILE is a gentle and straightforward procedure that doesn’t last longer than 10 -15 minutes in total. The laser only lasts for 30 seconds. So, patients won’t have to feel any pain in the entire process.  

Meanwhile, there can be a slight disturbance while performing a SMILE procedure as the small laser opening size can make things uncomfortable for the eyes.  If you choose the SMILE vision correction option, you may experience cases of severed nerves, dry eye, and eye infection. If all that happens, it would be at a very minimal level. 

After the SMILE vision correction procedure, you can be sure of a perfect vision that can last for a lifetime. You can resume your daily hobbies such as driving, watching movies, running, showering, and even applying makeovers within a few days after an expert a=gas conducted SMILE surgery for you.
