LASIK is a two-step procedure. Some surgeons prefer to conduct the first step using a manual bladed instrument, others prefer a femtosecond laser. Whichever the tool, the purpose of this step is to move aside the top layers of the cornea, to allow the second step to take place. While on the operating bed, you will fixate on a target light to keep the eye steady. A device will keep your eyelids open. This may be uncomfortable at first but patients tend to get used to the sensation.
The first step of the procedures forms a hinged flap of corneal tissue. This is moved aside to allow an excimer laser to be applied to the underlying corneal layers in a process called photoablation. Guided by computer, the laser removes selected, pre-calculated areas of tissue to reshape the cornea. This is to change the way light bends through the cornea so that light rays focus to a clear point on the retina. The corneal flap is then repositioned and allowed to self-seal.
After surgery, your clinical team will provide you with care instructions, medicated eye drops, and a protective eye shield. Vision is generally noticeably better within the next 24 hours and will further stabilise over the coming weeks.
