LASIK (Laser-Assisted-In-Situ-Keratomileusis) combines two techniques of surgery to correct refractive error. First, a laser called a femtosecond laser or a surgical blade called a microkeratome creates a thin flap in the cornea. Next, an excimer laser sculpts the underlying cornea into a new shape to correct the refractive error. The flap is then repositioned and adheres on its own without sutures after only a few minutes. Eye drops and/or ointment are placed in the eye to facilitate the healing process. Vision recovery typically is rapid. You will be given special eye drops and medicine after the surgery to minimize the risk of infection and improve comfort. Although you only need one day in Korea for this procedure we recommend you stay at least 3 days so you can have a check up afterwards.
LASEK (Laser-Assisted-Epithelial-Keratomileusis) corrects nearsightedness, farsightedness, and astigmatism. It is similar to PRK except that the surface layer (the epithelium) is replaced after surgery as a sort of bandage. Both PRK and LASEK are similar to LASIK in that they use the excimer laser to shape the cornea, but unlike LASIK neither procedure preserves the surface layers. PRK and LASEK are sometimes recommended instead of LASIK for people with thin corneas because they do not penetrate as deeply into the eye’s surface. In LASEK, the epithelium is loosened and peeled back to expose the cornea. The excimer laser then reshapes the cornea and the epithelium is placed back into position. Like LASIK, recovery time is rapid but discomfort is somewhat increased compared to LASIK. Our doctors can advise you which type of procedure is better for you.
SMILE (small incision lenticule extraction) uses a femtosecond laser to separate a thin lenticule (or disc) of corneal tissue from within the cornea. This disc is then removed through a very small incision and the net effect on the corneal shape corrects the Dave’s short-sightedness (or myopia). There is no corneal flap created and no tissue vaporised. One theoretical advantage of SMILE over LASIK is that it is less disruptive to the corneal surface, with just a small extraction wound instead of a flap. This is not to say LASIK is dangerous, it is extremely uses a femtosecond laser to separate a thin lenticule (or disc) of corneal tissue from within the cornea. This disc is then removed through a very small incision and the net effect on the corneal shape corrects your vision. This is not to say LASIK is dangerous, it is extremely safe. SMILE is a modern and popular technique but the price is higher than LASIK or LASEK.
A cataract is a painless, cloudy area in the lens of the eye. The lens is enclosed in a lining called the lens capsule. Cataract surgery separates the cataract from the lens capsule. In most cases, the lens will be replaced with an intraocular lens implant (IOL). Surgical methods that remove the cataract as well as the front portion of the lens capsule (anterior capsule) are used. The back of the lens capsule (posterior capsule) is left inside the eye to keep the vitreous gelin the back of the eye from oozing forward through the pupil and causing problems. The posterior capsule also supports the IOL and helps keep it in the proper position.
You shouldn’t wear contact lenses for a week before your eye exam. At the clinic, you will have an eye exam which takes about 1 hour. The doctor and assistants will analyse your results and give your options. You can choose to restore your vision on the same day or wait until the next day or a time when you are free. When you are ready for surgery, you will be given eye drops which will numb your eyes, you put on the gown and go in for the surgery. The surgery is over in 10-20 minutes usually from start to finish and your vision is restored! You can rest in the recovery room until you feel ready and then the doctor will give you one final eye check. Once you are ready to leave, we will accompany you to the pharmacy to get the medicine you need to take to fight any risk of infection and improve the healing process. Seoul Guide Medical will be there through the entire process.
