Why is the right eye blurry after the laser eye, but the left eye is fine

Do you have high prescription eyes? If it's 600 degrees, you'll have to pay attention.

The principle of LASIK is to make a flap at 130-160um (1um is 1 1000 mm) on the cornea, which is equivalent to a concave lens on the cornea, and to correct myopia by changing the curvature of the corneal stroma. However, the corneal stroma cannot be cut indefinitely, and a certain safe thickness must be retained, generally recognized as 410um (there is no definite evidence so far), or in other words, the thickness of the corneal stroma must be retained above 250, otherwise keratoconus will appear. The corneal thickness of a normal person is about 500 to 600um, and for every 100 degrees of myopia, the depth of 14um should be cut according to the cutting diameter (cutting range), and 12 units should be cut every 100 degrees, in addition, the thickness of astigmatism should be cut is the same as myopia.

Therefore, the deeper the power, the more likely it is to be dangerous. Since 410 is a lower limit, people with myopia and astigmatism of about 600-800 degrees are generally on the verge of this lower limit after cutting, and it is easy to have problems.

A normal cornea is sufficient to resist the pressure of intraocular pressure on the cornea. And because LASIK cuts corneal tissue, if the corneal tissue cannot withstand the pressure of intraocular pressure on the cornea, there will be problems, so you should pay attention to your eyes and don't overuse your eyes, otherwise it is really possible**.

Several of my classmates also went to get eye shots, and they usually pay attention to their eyes, carry eye drops with them, carry clean paper handkerchiefs, and pay attention to eye hygiene.

That's all I know, and I'm going to go to the eye these days, so I'm asking about it every day.

Why is there a question that is the same as this one, it's all you, and that's also mine Hehe.

After nearly 20 years of continuous development and improvement, excimer rock staring laser myopia has become a mature ophthalmic technology. At present, there are three common surgical methods in the world: PRK, LASEK, and LASIK.

Each of these three methods has its own advantages and disadvantages, and is suitable for different groups of people. Professor He Yanjin, director of the Department of Ophthalmology of the Second Hospital of Tianjin Medical University, reminded myopia patients that the choice of laser correction must be combined with their own eye conditions, and they should listen to the doctor's advice and choose the most suitable surgical method for themselves.

PRK surgery is the most basic method of laser myopia surgery, which can correct myopia and astigmatism at the same time, and can also correct farsightedness, its advantages are simple and easy, and there are few intraoperative complications, and the disadvantages are postoperative pain, slow vision recovery and corneal scarring in a very small number of people, which is suitable for correcting low-grade myopia. LASEK surgery is a modified procedure for PRK, which reduces the chance of postoperative pain and scarring, and is especially suitable for patients with high myopia with insufficient corneal thickness. LASIK surgery, i.e., excimer laser in situ keratomileusis, is developed on the basis of PRK, which first uses a precision automatic corneal lamellar knife to make a corneal flap, opens the corneal flap and irradiates the corneal stromal layer with a laser to flatten the cornea to correct myopia, and finally covers the corneal flap back to complete.

This surgery has no shortcomings after PRK surgery, high accuracy, more reasonable design, more in line with the anatomical and physiological characteristics of the cornea of the human eye, faster recovery of postoperative vision, better stability, only mild discomfort in the eye after surgery, the discomfort is eliminated after 1 day, and it is a myopia correction technique commonly respected by ophthalmologists at present. This auspicious jujube removal method is suitable for high, medium and low myopia, farsightedness and astigmatism.

After the operation, under the guidance of the doctor, use antibiotic eye drops to prevent infection, in addition to the auxiliary use of eye drops to promote wound healing, avoid splashing soapy water, shampoo, hair dye and other irritating liquids into the eyes within a week, do not rub your eyes within a month, do not swim, do not smoke, do not drink alcohol within three months, especially emphasize that after the operation, we must overcome bad eye habits, avoid long-term reading and reading on the computer, and reading in a low-light environment, lying down and other bad habits.

Let's change a few more hospitals, and you can use some sodium hyaluronate eye drops to relieve it.
