Does Lasik Make you Need Reading Glasses
LASIK is a laser-based vision correction procedure that allows having clearer vision since it can correct microscopically visible imperfections caused by hyperopia, myopia, and astigmatism. There are numerous questions you could have about LASIK among the most crucial is the one about “Does Lasik Make you Need Reading Glasses.” Find out more in the following article.
In the article “Does Lasik Make you Need Reading Glasses”, you will find more additional information such as, had lasik now need reading glasses, difficulty reading after lasik, computer glasses after lasik, and how long after lasik will i need glasses.
So, let’s look at the full review of Does Lasik Make you Need Reading Glasses, below.
What is LASIK surgery?
LASIK ( laser-assisted in situ keratomileuses) is one type of refractive surgery, namely eye surgery that aims to correct refractive errors (refracting) in the eye. LASIK eye surgery can treat nearsightedness (myopia), farsightedness (hypermetropia), and cylinder eyes (astigmatism).
LASIK procedures rely on laser technology that is used to correct the shape of the curvature of the cornea so that the eye can focus light on the retina precisely.
The cornea is located at the front of the eye and functions to capture light to be passed on to the retina which is at the back of the eye. The retina will later deliver light signals to be processed into images in the brain.
In this procedure, the eye surgeon creates a flap, which is a thin layer or fold of the cornea. The surgeon then refolds the flap, then using a laser the corneal tissue located under the flap will be scraped away until the cornea forms a normal curvature.
For people with nearsightedness, LASIK surgery is used to flatten the cornea that is too sharply curved. However, for farsighted people, refractive surgery is performed to add to the curvature of the cornea that is too flat. LASIK eye can also correct an irregular cornea to normal for people with astigmatism.
How is the LASIK eye procedure done?
Eye LASIK is performed with a device called an excimer laser in an outpatient surgery room. First, the eye will be given a few drops of a topical anesthetic to numb it.
An eyelid holder is placed between the eyelids to keep the eye open and prevent the patient from blinking. A suction ring is put on the eye’s surface to flatten the cornea and keep your eye from moving.
The patient may feel pressure from the lid holder and suction ring, this is similar to a finger pressed firmly against the eyelid. When the suction ring is placed in the eye, the vision will be dimmed or darkened.
After the cornea is flattened, a flap of the corneal tissue is formed using a microsurgical device, such as a laser or scalpel. The corneal flap is then removed and folded back. After that, the excimer laser will measure the eye before being programmed.
The doctor will ensure whether it is placed in the proper location. After the laser cuts through the corneal tissue, the doctor then places the flap back in and smoothes the sides.
The flap will adhere to the corneal tissue in 2-5 minutes without the need for stitches. After the operation is complete, the doctor will provide eye drops and eye protection to protect the eyes from friction. Vision restoration after LASIK surgery will take 3-6 months after surgery.
Fore performing LASIK eye surgery, you should do the following:
Do not wear soft lenses for 2 weeks before the initial evaluation.
- Not wearing toric soft lenses or rigid gas permeable (RGP) lenses for 3 weeks before the first evaluation.
- Do not wear hard lenses for 4 weeks before the first evaluation.
- Do not use various creams, lotions, make-up, and perfume the day before surgery.
