How to treat cataracts after retinal detachment 20

Cataract patients want to choose the "best" intraocular lens before surgery, and even think that the most expensive intraocular lens is the best, I am afraid that choosing the wrong lens will affect the postoperative vision, this worry is completely unnecessary. We already know that the implantation of an intraocular lens into the eyeball replaces the function of the original lens, and plays the role of focusing and imaging in the original position, so that the eye can see objects clearly. Therefore, whether it is a domestic intraocular lens or an imported intraocular lens, as long as the material used to make the intraocular lens is non-toxic, the process is excellent, and the disinfection is strict, the effect is the same after implantation in the eye.

Moreover, at present, most of the raw materials, production equipment and processes of domestic intraocular lenses are basically the same as those of foreign manufacturers, and they are much cheaper than imported intraocular lenses in the first place, so under the premise of ensuring quality, domestic intraocular lenses and imported intraocular lenses have the same effect in cataract surgery to restore vision, and it is not the most expensive is the best.

Retinal detachment, if detected in time and carried out early**, generally does not lead to complications of cataracts. If the patient is not detected in time and does not have surgery in time, the eyeball is in a state of low intraocular pressure for a long time, which will affect the production of aqueous humor and some metabolic disorders. In this way, the nutrition of the lens will also be affected, and cataracts will develop over time.

Therefore, once there are symptoms of retinal detachment, such as decreased vision, a sense of obstruction in front of the eyes, and deformed vision. We must go to the hospital in time to let the doctor do a detailed ophthalmic examination, such as checking the fundus or doing B ultrasound to find retinal detachment, and surgery as soon as possible**, which can not only save vision, but also prevent some complications like cataracts.

Workers who are engaged in close proximity are prone to difficulty in looking at the words in close proximity.

treatment of congenital cataracts; Don't delay the operation anymore, otherwise when you are older, even if the operation is successful, it will be difficult to improve your vision, because congenital cataract is often accompanied by form deprivation amblyopia, and the best time for amblyopia** is before the age of 6.

At present, China's cataract surgery has been very mature and has reached the international level, as long as you go to a qualified doctor in a regular hospital to carry out the operation, unless there are very few cases, it should be said that there will be no danger, and there will be no sequelae.

Congenital cataract, postoperative "posterior cataract" may occur, because children's lens cortex is prone to hyperplasia, which is common, if it happens, it is OK to hit the posterior capsule with a laser, it only takes 1-2 seconds, there is no feeling, and there is no danger.

Force. Initial cloudiness has little effect on vision, and then gradually worsens until it significantly affects vision and even blindness.

Attention should be paid to cataract surgery; Young people are prone to posterior capsule opacity after surgery, which is the so-called posterior cataract, which will affect vision, but it will be fine immediately after the laser, and it is estimated that you will use the laser ** for this purpose. There's nothing in particular to pay attention to now. Vision can only remain the way it is now (I don't know how much you had better correct your vision now), your vision in the future will not be improved compared to your current vision, but your vision will not decline without other special circumstances, you have already had a laser, and you don't need to play a laser in the future, you can rest assured, it should be very optimistic.

It is better to have early surgery for congenital cataracts, at least in the preschool years, because congenital cataracts can easily develop form-deprivation amblyopia and can be avoided by early surgery.

Now cataract surgery can be performed by phacoemulsification, folding intraocular lens implantation, the inchement can be as small as a millimeter, and the whole process of surgery can be completed in 5 minutes.

Retinal detachment to do fundus and vitreous examination, surgery is the only way, my suggestion is to use 90d slit lamp prescopy will see this situation very clearly, and dilated pupils to examine the fundus in detail, ** The principle of retinal detachment is to close the tear, and there will be no sequelae after good postoperative recovery (except for the sequelae and complications of the original disease), if the recovery is not good or timely, it is not closed for a long time, and the omentum is not reduced, which will eventually lead to eye atrophy and blindness, the sooner the operation, the less difficult it is, if the weeks and months are not ** It is recommended that you find a way to be hospitalized for surgery as soon as possible, retinal detachment can generally be cured, but it must be surged, it is useless to use any drugs, and it must be operated on as soon as possible, without delay. The larger the area of detachment, the greater the difficulty of surgery, so hurry to the hospital and do not delay.

First of all, retinal detachment is a fundus disease, so you need to have an eye check-up. Check the lower fundus, cornea, visual acuity, etc. Cataract is the clouding of the lens in the eye from transparent to opaque, which prevents light from entering the eye and thus affects vision.

Initial cloudiness has little effect on vision, and then gradually worsens, significantly affecting vision and even blindness. Cataract surgery is a relatively sophisticated ophthalmology surgery, and in order to ensure the effectiveness of the surgery, adequate preoperative examination is required. The pre-cataract surgery examination is divided into two parts, namely the eye examination and the whole body examination.

Eye examinations generally include visual acuity, visual function, intraocular pressure and lacrimal duct, corneal curvature, ultrasonography and ultrasonography, where corneal curvature and ultrasound are used to calculate the power of the intraocular lens to be implanted during surgery. In the development of cataracts, if not timely, there will be many serious complications, such as glaucoma, pigmentitis, etc., these eye diseases mostly occur in the middle and late stages of cataracts, such as swelling and overmaturity, which can not only cause blindness, but also sometimes cause severe inflammation in the eye, resulting in eye atrophy; Some patients may be unable to tolerate long-term eye pain and have to have an enucleation of the eyeball. Therefore, it is a reminder that cataracts must be operated on to a certain extent.

Problem Analysis: Hello, cataract surgery has nothing to do with retinal detachment. Retinal detachment is a direct separation of the retinal neuroepithelial layer and the pigment epithelial layer of the fundus, and retinal detachment can be caused by peripheral retinal tears or vitreous traction.

Suggestions: It is recommended to examine the fundus condition in detail, clarify the cause of retinal detachment, and retinal reduction in time to restore vision.

Retinal detachment is a condition that severely impairs vision and generally requires prompt surgery** to preserve residual vision. Common surgical methods include episcleral cerclage and vitrectomy. Extrascleral cerclage, also known as external surgery, is a less invasive surgery that does not cause cataract progression, and does not require a second operation, which is suitable for patients with milder disease, but this surgery may cause myopia to deepen.

You may also need to wear appropriate glasses after surgery.

Another type of surgery is vitrectomy, which may need to be filled with silicone oil or air after the surgery, which can easily cause cataracts. Generally, vitrectomy surgery is a more severe retinal detachment, so the occurrence of cataract is difficult to avoid.

1. The cataract surgery time is about 15 minutes, and the real operation time is only 2-3 minutes for doctors with rich clinical experience and skilled doctors.

2. Retinal detachment surgery is fundus surgery and is more complicated. The surgery takes a relatively long time, and it is possible to do so for 1-2 hours.

Secondary cataract refers to a special condition in which the lens cortex remains in the pupil area or forms a fibrous membrane after the 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. Symptoms of Secondary Cataract Patients with secondary cataract usually present with decreased vision in one or both eyes, often accompanied by or have had symptoms of primary eye diseases such as eye redness, pain, photophobia, tearing, and eye swelling.

Lens opacity is caused by a disease of the posterior part of the eyeball, granular gray-yellow opacity appears in the posterior pole capsule and posterior subcapsular cortex, and more vacuoles are formed, which can be confined to the axial part for a long time, and then gradually expand to the center and periphery of the lens nucleus, forming radial chrysanthemum-like opacities. Then it spreads to the anterior cortex, gradually causing the lens to be completely cloudy, and then water absorption, the capsule becomes thicker, the lens shrinks, and there are calcifications and other changes. Most cases caused by irisal cyclitis start from the anterior cortex, those caused by glaucoma mostly start from the anterior cortex and nucleus, and those caused by high myopia are mostly nuclear cataracts.

In addition, it is often accompanied by signs of the primary disease, such as annular posterior adhesions of the iris, glaucoma spots, etc. What should I do if I have a cataract after retinal detachment surgery? If the cataract has affected life and work due to reduced vision, surgery should be considered, and the current phacoemulsification surgery will not affect the fundus, and if the last mesh removal surgery was successful, the postoperative vision should be good.

Diabetes, omentum detachment, cataracts, then do OCT to determine the function of the omentum! If the omentum function is absent or weakened, cataracts are done, and there is no vision.

Analysis: Retinal detachment does not cause cataracts. As far as is currently understood, the onset of senile cataract may be related to the following factors:

1) Nutrient metabolism Through animal observation, it was found that certain vitamin and trace element deficiencies are related to cataract formation, such as calcium, phosphorus, vitamins E, A, B2, etc.

2) Sunlight and ultraviolet rays Over the years, it has been noted that sunlight is involved in the formation of cataracts in humans. Under the influence of ultraviolet light, phosphorus ions may combine with calcium ions in the aging lens to form insoluble calcium phosphate, which leads to hardening and calcification of the crystals. At the same time, ultraviolet rays also affect the redox process of the lens, which promotes the denaturation of lens proteins and causes cataracts.

3) Outside temperature According to the survey of foreign scholars, the incidence of cataract in workers over 60 years old who work in high temperatures is significantly higher.

4) Hypoxia In the case of hypoxia, sodium and calcium in the crystal can increase, potassium and vitamin C can decrease accordingly, and lactate increases, which promotes the formation of cataracts.

5) Endocrine Endocrine disorders can promote the production of cataracts, which is enough to explain that the incidence of cataracts in diabetic patients is higher than that of the general population.

6) Hardening and dehydration In the case of dehydration, the body fluid metabolism is disordered, and some abnormal substances will be produced to damage the crystals. Animal experiments have proved that after hypertonic dehydration, the crystals appear empty.
