It has been two years since cataract surgery, and I always have dry eyes, what should I do?

Dry eyes after cataract surgery can be relieved by general**, drugs**, etc., it is recommended that patients after cataract surgery pay attention to eye rest and avoid looking at mobile phones, computers, TVs and other electronic products for a long time.

1. General**:

If the dry eyes after cataract surgery are not very severe, you can use a hot towel to apply a hot compress to the eyes, which can promote blood circulation in the eyes and relieve the symptoms of dry eyes, but do not use hot water to avoid damage to the eyes.

It can also be relieved by dietary conditioning, you can eat more vitamin-rich foods, such as apples, carrots, spinach, etc., which can supplement the body with the nutrients it needs and improve the condition of dry eyes. In daily life, excessive eye use should also be avoided, attention should be paid to eye rest, and good eye habits should be maintained;

2. Drugs**: Dry eyes after cataract surgery, if it cannot be relieved by general**, and the degree of dry eyes is more serious, patients can use drugs under the guidance of doctors**, such as sodium hyaluronate eye drops, compound sodium chloride eye drops, etc., which can relieve the symptoms of dry eyes. Disinfect your eyes and hands before using the drug to avoid eye infection.

Causes of cataracts: Different cataracts have different causes, and posterior cataract refers to a special state in which the lens cortex remains in the pupil area or forms a fibrous membrane after cataract is surgically removed or partially absorbed by the traumatic cataract cortex.

This complication is particularly prevalent and serious in early intraocular lens implantation procedures where the importance of lens epithelial cell and cortical clearance is not well understood. Metabolic cataract is an endocrine disorder, also known as diabetic cataract, which is caused by the biochemical abnormality of the internal environment caused by the rise of blood sugar caused by diabetes, which leads to the formation of cataract, and is more common in the case of congenital metabolic abnormalities.

If there is dryness of the eyes after cataract surgery, it is best to apply a local hot compress and use eye drops to relieve dry eyes, the most commonly used now is sodium hyaluronate eye drops or polyvinyl alcohol eye drops, of course, you can also use horse chestnut digitalis eye drops, or recombinant bovine alkaline fibroblast growth factor eye drops, these effects are also good, but be sure to use the medicine under the guidance of a local doctor.

The reason why the eye is dry after this surgery is that the tear film may be damaged during the operation, so after the operation, the tear film is not very stable, so the eye is dry.

After cataract surgery, you also need to go to the hospital regularly for re-examination to see the specific condition of the eyes, and at the same time improve the tear secretion test and the tear film breakdown time to see the degree of dryness of the eyes.

The sequelae of surgery are not well resolved.

Dr. Li Yongcheng appealed to patients to pay more attention to the symptoms of dry eye after surgery because of aging, and cataracts are more likely to occur in the elderly.

According to the statistics of the National Institutes of Health, from 2001 to 2013, the rate of cataracts in the elderly over 65 years old exceeded 30%, which has become a major threat to the vision of the elderly; Fortunately, surgery** is now the main way to restore vision and cataracts**.

Dry eye symptoms after cataract surgery are relieved with preservative-free artificial tears

According to a 2017 study in the United States, more than half of the elderly who had cataract surgery** with an average age of 70 years old had dry eye symptoms when undergoing preoperative testing.

Dr. Li Yongcheng of the ophthalmology clinic pointed out that a 70-year-old woman had poor vision due to cataracts, and successfully recovered her vision after surgery, but she had dry eye symptoms, including a foreign body sensation and tears when blinking.

Eye surgery can cause dry eye symptoms directly or indirectly

According to Dr. Li Yongcheng, the symptoms of dry eye caused by cataract surgery may be caused by the loss of corneal epithelium before surgery, corneal epithelial damage during surgery, inflammatory reaction or tissue edema after surgery, or decreased stability of the mucus layer due to uneven surgical wounds.

In addition to the symptoms of dry eye after cataract surgery, Dr. Li Yongcheng also mentioned that myopia laser surgery, glaucoma surgery, corneal transplant surgery, retinal peeling surgery and other surgeries that affect corneal tissue are also easy to directly cause dry eye symptoms.

Dry eye symptoms after surgery should be consulted as soon as possible

Dr. Li Yongcheng appealed to patients to pay more attention to the symptoms of dry eye after surgery because of aging, and cataracts are more likely to be resistant to the elderly due to aging. In addition to normal work and rest, adequate sleep, intake of fruits rich in vitamin C, and reducing the time spent using 3C products, improving lifestyle habits and sometimes applying warm compresses to the eyes can help dry eye symptoms. Of course, the most important thing is to go to the ophthalmology clinic as soon as possible after you notice the symptoms, and you can get the right medicine to improve it.

If cataract is dry after surgery, you should contact the doctor in time for a re-examination, do not blindly use medicine, there may be problems with your eyes, so it is better to consult a doctor.

After cataract surgery, patients often experience symptoms of dry and uncomfortable eyes, which may be caused by surgery-induced dry eyes, and often need to go to the hospital to check the amount of tear secretion and tear film break-up time.

According to the results of tear secretion and tear film breakup time to choose the corresponding artificial tears, if the amount of tear secretion is not enough, it is often necessary to choose a little diluted artificial tears such as Haylu, Aili, etc., if the tear film breakup time is relatively short, we often need to choose a viscous artificial tears application, such as Siran, for severe dry eye patients, the amount of tear secretion and tear film breakup time are relatively abnormal, and it is often necessary to choose two eye drops to be applied together.

You need to go to the hospital to find a doctor to prescribe medicine, and you can't use eye drops outside.

There are several reasons for vision loss after cataract surgery in the elderly:

1. Presbyopia or myopia, etc.

Presbyopia is a common phenomenon of eye aging in the elderly. The lens of a normal person has a self-regulating function, which allows us to see both distant and close objects. However, the intraocular lens power after cataract surgery is fixed, and it is not possible to see both distant objects and near objects, either you can see near but not far, or you can see far but not close.

In order to achieve better vision, patients can usually go to the hospital for glasses 3 months after the surgery has healed.

2. Posterior cataract.

Some elderly cataract patients have good vision after surgery, but after a few months or years, their vision decreases again, and they mistakenly believe that they have developed cataracts again. It is impossible for cataracts to grow back after surgery, but there is a condition called posterior cataract that can cause a patient's vision to deteriorate after surgery. This situation is manageable.

3. Temporary surgical complications.

After cataract surgery, due to the influence of the incision, the curvature of the cornea will undergo some changes, and there will often be a certain degree of astigmatism after the operation, which will affect the vision. There is also a relatively rare situation, that is, about 2 months after the operation, the vision will be reduced and accompanied by visual deformation, medically known as macular cystoid edema, which is a mild complication after cataract surgery, which will generally subside on its own in about 6 months, and does not need to be **.

4. Other lesions on the eye.

One of the most common reasons is that cataract surgery, no matter how successful the surgery is, it may not improve vision if there is a severe fundus disease before the surgery. Generally speaking, before surgery, the doctor should examine the patient's red-green perception, light positioning, B-ultrasound, visual electrophysiology and other items, because the lesion of the cataract itself also affects the doctor's observation and diagnosis of other eye diseases such as glaucoma and macular degeneration. In addition, if the cornea has lesions such as dystrophy or corneal degeneration, it can also affect the vision after cataract surgery to a certain extent.

After cataract surgery, due to the influence of the incision, the curvature of the cornea will undergo some changes, and there will often be a certain degree of astigmatism after the operation, which will affect the vision. At this time, three months after the operation, after the wound has healed, optometry can be performed.

In addition, corneal endothelial damage is caused during surgery, corneal edema occurs after surgery, and blurred vision can also occur after cataract surgery. This condition can be actively treated with eye drops containing hormones, which usually recover within one to two weeks.

In addition, there is a relatively rare condition in which vision loss accompanied by visual distortion occurs about two months after surgery, which is medically known as cystoid macular edema. This is a mild complication after cataract surgery that usually resolves on its own in about six months.

Condition analysis: cataract is to take out the lens of the lesion, and then install an intraocular lens, guidance: so after the operation, different to meet the clear vision of the whole process, the operation can not reach completely normal, which is not unsuccessful.

There are several causes of vision loss after cataract surgery.

1. Inaccurate intraocular lens measurement guidance for patients undergoing cataract surgery During cataract surgery, in order to better insert the intraocular lens, the transparent lens posterior capsule is retained to play a supporting role, and most people will no longer have opacity, but some patients can produce opacity and affect vision.

In fact, a common cause is that the residual cortex and epithelial cells that fall off the posterior capsule of the lens are still proliferating, forming a translucent membrane in the pupil area, which is medically called posterior cataract. Posterior cataract is not only related to residual cortex and age. It is also related to the intraoperative implanted intraocular lens, and the imported Johnson & Johnson Eyesight series intraocular lens has significantly inhibited the occurrence of posterior cataracts.

What are the clinical manifestations of posterior cataracts?

1.progressive decline in visual acuity, poor corrected visual acuity;

2.The posterior capsule is opaque and has white organic tissue of varying thickness, and there may be posterior iris adhesions;

3.The degree of visual impairment depends on the thickness of the mechanizing membrane.

Doctors can find different degrees of opacity and thickening of the posterior capsule through dilated slit lamp examination, and at the same time exclude fundus lesions to diagnose, for posterior cataract that affects vision, YAG laser posterior capsulotomy is the only way to improve vision. For patients with a long onset of posterior cataract and a significant thickening of the turbid posterior capsule, which cannot be cut by laser, surgery is required to cut off the turbid posterior capsule.

There are many cataract patients who will be accompanied by fundus disease, and cataract surgery alone cannot achieve normal vision, and it is generally necessary to continue fundus disease after surgery to recover part of the vision.

They have some antagonistic effect on the progression of cataracts, so patients can eat more fresh vegetables and fruits, as well as foods rich in these vitamins.

Hello, there are several reasons for vision loss after cataract surgery.

1. The measurement of the intraocular lens power of the patient undergoing the first cataract surgery is inaccurate 2. During cataract surgery, in order to better insert the intraocular lens, the transparent posterior lens capsule is retained to play a supporting role, and most people will no longer have opacity, but some patients can produce opacity and affect vision.

1. Surgical incision.

Cataract surgery has a small incision that can cut nerve fibers, causing decreased corneal sensation and reduced blinking, which can cause dry eye.

2. Surgical operation.

Cataract surgery procedures include topical anesthesia, conjunctival sac irrigation, microscope light irradiation, etc., all of which will cause more or less subtle damage to the ocular surface, and the longer the operation time, the more serious the injury.

3. Eye drops.

The eye drops contain preservatives, which can destroy the lipid layer of the tear film, shorten the time for the tear film to break, and affect the stability of the tear film.

It is recommended that once the patient has persistent pain, he should go to a regular medical institution for examination as soon as possible, until the symptom is confirmed, and avoid taking drugs without authorization, so as not to affect the recovery of the disease.

After cataract surgery, the tear film of patients will change significantly, especially on the first and second days after surgery, the stability of the tear film will be greatly reduced, the tear film breakup time will be significantly shortened, and the degree of corneal fluorescein staining and tear secretion will be significantly increased. At the same time, the morphology of the lipid layer of the tear film was also significantly damaged, and the secretion of tears did not basically return to the preoperative level until 7 days after surgery

1) Topical anesthetics cause punctate detachment of corneal epithelium and decreased tear film stability.

2) Intraoperative mechanical damage to the corneal epithelium, postoperative inflammatory reaction, tissue edema, wound healing and local bulge of the surgical incision all affect the adhesion function of the tear film mucus layer to the eye surface epithelium, resulting in a decrease in tear film stability.

3) The hyaline corneal incision causes the transport of acetylcholine and cholinesterase in the nerve fibers around the incision to be impaired, resulting in local corneal sensation loss.

4) In the early postoperative period, patients frequently used preservative-containing eye drops to promote the retention of preservatives in the conjunctival sac, which had a continuous toxic effect on corneal epithelial cells, changing the permeability of cells, and thus affecting the function of tear film.

5) The application of glucocorticoid eye drops after phacoemulsification cataract aspiration will promote the decomposition of fat and protein, and destroy the stability of the tear film to a certain extent, resulting in a shortened tear film breakdown time and a decrease in tear secretion.

6) Many patients with senile cataract also have diabetes mellitus, and the tear film function of diabetic patients is poor, and they are susceptible to dry eye syndrome.
