How long does it take for vision to be restored after laser correction?

Laser vision correction is one of the simplest and yet very effective methods of vision restoration, characterized by a fairly quick recovery period. However, due to the individual characteristics of each patient’s body, it is important to understand the specifics of the procedure and follow all recommendations of specialists.

Most excimer laser methods for vision restoration are performed on an outpatient basis under local anesthesia. After the operation, the eyes recover very quickly, so it makes no sense for the patient to stay in the clinic for more than one or two hours. The ophthalmologist conducts a follow-up examination and, if the person’s condition is normal and the corneal flap fits correctly, he sends the patient home with absolutely healthy vision.

Contraindications for laser vision surgery

Despite the fact that laser intervention to improve vision is performed quite quickly and painlessly, there are some limitations to such a procedure. After a comprehensive examination of the patient’s eye health, the doctor will refuse to perform surgery if:

• cataract and glaucoma;
• post-surgical retinal detachment after previous operations;
• retinal dystrophy;

• inflammatory eye diseases;
• high degree of progressive myopia (myopia);
• changes in the fundus of one or both eyes;
• presence of diabetes mellitus;
• infectious diseases of the visual system;
• pregnancy and breastfeeding;
• immunodeficiency states and autoimmune pathologies (collagenosis, arthritis).

Preparation for laser vision correction surgery

In order for the procedure to be successful and the result to be effective, the patient undergoes a thorough examination by specialists (ophthalmologist and therapist). It is necessary to pass the prescribed tests, which most often include a general blood test, as well as tests for hepatitis B and C and the presence of HIV infection.

It is important to remember that before the operation you should not wear contact lenses (hard ones for several weeks, soft ones for one week). And two days before the procedure, it is strictly prohibited to drink alcohol, and it is not recommended to use eye cosmetics 24 hours before the procedure.

Types of operations and indications for surgical correction

Modern ophthalmological microsurgery has a large arsenal of surgical interventions to correct myopia. There are no absolute indications for such operations. Of primary importance is the patient's desire to see well without glasses or contact lenses.

In this article we will consider the following types of operations to correct myopia:

1. Anterior radial keratotomy . Its essence lies in the mechanical removal of part of the cornea to change its refractive power in order to more correctly focus light rays on the retina. The best results after such an operation are achieved in patients with myopia from 1.5 to 6.0 diopters. For patients with readings less than 1.5 diopters, such manipulation is not recommended due to the risks of excessive correction. If the threshold of 6.0 diopters is exceeded, the probability of obtaining an acceptable result is low. For people under the age of 21, radial keratotomy is not performed due to unstable refractive indexes. People whose expected correction level with glasses does not reach 20/40 rarely undergo this operation. We are talking about patients with amblyopia, maculopathy, myopia with a history of retinal detachment, as well as macular degeneration.
2. Myopic keratomileusis . The indication is myopia over 6 diopters. The essence is to form a flap, after bending which part of the corneal stroma is removed. Before such an operation, a comprehensive examination of the organ of vision is necessary, including measurement of the thickness of the cornea. Age restrictions are the same as in the previous paragraph.
3. Excimer laser correction involves changing the shape of the cornea using laser exposure. Instead of being removed by surgical instruments, the corneal stroma is vaporized by laser beams. This method has proven itself to be effective in correcting myopia up to 6.0 diopters.
4. Removal of the clear lens is the operation of choice for patients with a high degree of myopia (10 diopters and above), as well as when it is impossible to perform surgery on the cornea due to its insufficient thickness. In order to change the refraction, the patient's own unchanged lens is removed, and an artificial lens with the required optical power is installed in its place.

Rehabilitation after laser vision correction

To ensure that the process of restoring vision after surgery is quick and easy, the patient should strictly follow absolutely all the doctor’s recommendations. In addition, there are simple rules that, if followed, will make the patient feel better. So, you should not touch the operated eye for at least a day. You cannot wash your face or hair for three days. For two weeks, the patient must avoid bright light, as well as eye contact with excessively cold/hot air. It is worth, among other things, to exclude the use of not only decorative eye cosmetics (mascara, eye shadow, pencil), but also skincare. It is strictly not recommended to visit the swimming pool, solarium and sauna.

If the eyes heal without complications after laser vision correction, you will be able to return to a full life without restrictions within a month.

Good afternoon. After laser correction (farsightedness +2 was removed), I have been seeing everything enlarged for the second month. At first the picture narrowed, but for almost a month there were no changes. The doctor said it's a neuroadaptation. But I'm scared that nothing has changed for so long. Can swelling of the retina or macula give such an effect of enlarging objects? Maybe it's not a matter of adaptation at all? What should I do? Thank you in advance for your answer. (Vitaliya - May 2, 2020) Answer to the question: Hello! Surgical treatment of ametropia (myopia, farsightedness, astigmatism) may be accompanied by a change in the perception of the size of objects, especially with hypermetropia, for which spectacle or contact correction has not previously been used, but as a rule this effect is short-term. For a detailed answer to the question about the causes of your complaints, a full ophthalmological examination is necessary, including examination of the fundus with a wide pupil, and, if necessary, the use of modern instrumental research methods.

Is it possible to restore vision and what will be the result if diagnosed: High myopia, complex myopic astigmatism, moderate refractive amblyopia in both eyes. Peripheral vitreochorioretyl retinal dystrophy on the left, operated on by laser? I live in the Trans-Baikal region and would like to come for a consultation and surgery. Is there a need to come or is there nothing more that can be done in my case? (Evgeniy - January 19, 2020) Answer to the question: Hello Evgeniy! The possibility of laser correction is determined not only based on the degree of myopia and the presence of astigmatism, but also on the condition of the cornea (its thickness and curvature). Therefore, it is possible to determine whether surgery is contraindicated in your case only after a complete ophthalmological examination. The diagnosis of amblyopia implies that after the operation (if it is possible), visual acuity will not reach 100%, but will correspond to the degree of amblyopia (that visual acuity that is determined with maximum correction with glasses). Sincerely, ophthalmologist Vitaly Sergeevich Klyuganov. For more detailed information, as well as to make an appointment, you can call +7(495)781-93-33.

Is it true that wearing contact lenses for a long time can prohibit laser correction? I just heard that people who wore lenses for a long time were refused laser surgery. (Dmitry - July 26, 2019) Answer to the question: Hello Dmitry! The period of wearing contact lenses is not a limitation for laser correction. But often, against the background of prolonged wearing of contact lenses, dry eye syndrome develops, which can be the reason for refusing surgery.

Good day! Please tell me, after vision correction, looking with the left eye at luminous or reflecting objects (moon, windows, headlights..), a doubling effect to the left is observed. What could be the reason for this, please explain? (Vitaly - January 23, 2019) Answer to the question: Hello, Vitaly! After laser vision correction (especially in the dark), optical phenomena (light scattering circles, glare, flare) may appear from bright light sources (lanterns, oncoming car headlights). These phenomena do not affect visual acuity. During the first month after surgery, as a rule, patients stop noticing these effects (they stop paying attention, they get used to it). Their occurrence can be associated with various factors: the original shape and parameters of the cornea, the width of the pupil, and the inclusion of the transition zone of the optics (formed during the operation) in the pupil zone. Sincerely, ophthalmologist Patakhova Khadizhat Magomedovna. For more detailed information, as well as to make an appointment, you can contact us by phone. Opening hours: Monday - Sunday: from 10.00 to 20.00. Sincerely, Dr. Kurenkov Clinic

Approximately how much can laser correction surgery cost (of course, in the absence of contraindications after the examination) (Alexander - January 12, 2019) Answer to the question: Hello, Alexander! For myopia with similar diopters, laser vision correction is contraindicated in glasses. But in our clinic we can offer other methods of vision correction, such as implantation of phakic intraocular lenses or removal of the clear lens with implantation of a multifocal intraocular lens. The cost and appropriate method of surgery can be determined only after undergoing an in-person ophthalmological examination. Sincerely, ophthalmologist Elena Viktorovna Polunina. For more detailed information, as well as to make an appointment, you can contact us by phone. Opening hours: Monday - Sunday: from 10.00 to 20.00. Sincerely, Dr. Kurenkov Clinic

What needs to be done after surgery during the rehabilitation period?

In addition to the rules described above, which should be followed unconditionally, ophthalmologists also recommend paying attention to the following recommendations, which will also contribute to the rapid restoration of vision after laser correction:

• Regularly use drops prescribed by a specialist;
• Touch your eyes only with clean, washed hands, do this as little as possible;
• Do not drink alcoholic beverages;

• When outdoors, you should wear glasses with a UV filter;
• Do not wear things with a narrow neck that are pulled over your head;
• Avoid situations that may cause trauma to the eyes;
• Do not overstrain your visual organs with excessive reading, working on a computer or smartphone;
• Reduce physical activity, avoid going to the gym;
• Avoid places with a lot of tobacco smoke.

What is allowed during rehabilitation after laser surgery

In the first hours, it is important to remember that after the operation it is worth giving the visual organs a rest, so it is recommended to blink and close your eyes as often as possible, you can sleep, or just lie down to provide darkness to the iris. Doctors allow sleeping on your side. If you experience excessive tearing, you can gently dry your eyes with clean, dry wipes. Small amounts of visual stress in the form of reading, watching TV, using a telephone or computer (very dosed) are also acceptable. If you experience pain during the rehabilitation period after laser surgery, you can take analgesic and sedative medications, however, it is worth checking with your doctor which ones.

Contraindications after laser surgery

In order for the rehabilitation period to be successful and for no complications to arise after surgery to improve vision, it is necessary to follow some rules prescribed by experts.

• During the first three days, it is strictly not recommended to rub the eyes, even if the person experiences severe itching: this symptom means that the damaged corneal tissue is undergoing a healing process. Rubbing your eyes can injure your cornea.
• Restrictions after laser surgery also include visiting a bathhouse, sauna, swimming pool and long-term water treatments in the bathroom. Because moist hot air and water getting into the eyes can prevent them from healing.
• For the first few days after laser vision correction, you should not wash your face with strong streams of water. Do this very carefully, without using soap; it is best to wet a cotton pad with water and wipe the area around the eyes in a circular motion.

• Women are not recommended to wear makeup for 2-3 weeks; they should avoid using sprays and hairsprays after laser vision correction. This ban is explained by the fact that cosmetic residues and sprayed particles can get into the eyes and cause irritation in the vulnerable area.
• In the first week after laser surgery, ophthalmologists recommend sleeping on your back, since lying on your side or stomach will increase blood flow to the visual organs, which can affect the speed of healing. In addition, the last two poses can be traumatic for the eyes.

• To quickly restore vision after surgery, it is better to take only short walks, while wearing sunglasses with a good UV filter, which will help protect your eyes from excess light and ultraviolet exposure.
• In the first two weeks after laser surgery, it is necessary to completely avoid eye strain, that is, avoid reading, using a computer and gadgets. In the dark, it is advisable not to turn on the main lighting; it is better to use lamps.

For each patient, contraindications after surgery can be removed by an ophthalmologist individually, however, each of the instructions must be strictly followed for at least one week.

Since rehabilitation after successful laser vision correction lasts at least 30 days, it is optimal to adhere to the rules described above during this period. If the healing process is difficult for the patient, the ophthalmologist increases this period to 1.5 months.

Consequences of laser vision surgery

During the rehabilitation period, when vision is restored, the consequences may be different. Ophthalmologists include stars and glare as normal symptoms when the patient looks at the outside world; the eyes may dry out and a feeling of discomfort appears. That is why a specialist prescribes special moisture-stabilizing drops. Also, vision after surgery is subject to blurring, and the ability to see in poor lighting conditions deteriorates.

Periodically, the patient experiences conjunctivitis, hemorrhages and epithelial ingrowth (due to improper healing). However, if all recommendations are followed, the likelihood of serious complications will be reduced to a minimum.

Tips and recommendations before the procedure

Preparations are also required from the patient. There is a list of recommendations and instructions that will help you conduct the event comfortably, without unnecessary stress.

• The day before the operation you should not drink alcohol.
• On the day of the procedure, it is not recommended to apply makeup, use perfumes, lotions, varnishes, or aerosol deodorants.
• Doctors advise stopping using contact lenses 1-2 weeks before correction.
• For surgery, it is advisable to wear breathable clothing with a wide collar.
• When going to the hospital, the patient needs to take eye drops, if the ophthalmologist has already prescribed them, and sunglasses. Immediately after the manipulation, the eyes will be very sensitive to bright light.
• It is recommended to take an accompanying person with you, since for some time after the restoration of vision with laser correction, the patient will experience fog before the eyes.

Is it possible for vision to deteriorate after the procedure?

Before deciding to undergo surgery, many patients ask themselves: can laser correction worsen existing vision or completely deprive it of it? Scientific research and practical experience show that complete blindness cannot occur after such an intervention. However, a drop in refractive indices can occur if the corneal flap is cut incorrectly, which is removed with a special blade to access the eyeball in order to perform the necessary manipulations. Also, vision deterioration occurs when the depth of penetration into the cornea is incorrectly calculated. It happens that myopia (myopia) is replaced by hyperopia (farsightedness), and the refractive indices of astigmatism change. Such cases are very rarely observed in modern ophthalmological practice; additional laser vision correction may be required to eliminate them.

Occasional deterioration in visual ability may be due to failure to follow doctor's instructions during healing. For example, if you constantly touch your eyes or rub them, the corneal flap may move, which will lead to disruption of the light-conducting system of the visual organs. If vision decreases after surgery, you absolutely cannot leave everything as it is. You should immediately inform your doctor about this. He will determine the cause of the anomaly and take appropriate measures in the form of prescribing additional recovery procedures, prescribing medications or prescribing a repeat operation.
