Cataract forms when the crystalline lens of the eye develops an opacification. Lens of the healthy eye is transparent and light can pass through without effort. In case of cataract lens gets thicker and becomes cloudy. It is hard for the light to pass through it and vision is being blurred. Form and scope of the opacification of lens can differ. If opacification have established further from the centre of the lens, then you can sometimes leave the existence of cataract unnoticed. Cataract can be the cause of cloudy or blurred image. It can be compared to frozen or steamed window.
Glasses can help in the initial stage of cataract but surgical treatment is necessary when the loss of vision caused by the cataract encumbers normal everyday life. Removal of the opacificated lens is possible only through surgery.
During the surgery of the cataract the lens that has developed opacification is removed from the eye. It is replaced by the artificial intraocular lens or contact lenses, sometimes powerful glasses are used.
Local anaesthesia is usually used in the cataract surgery. Laser in the cataract removal surgery is not used.
Glaucoma is a progressive eye disease causing changes in the nerve of the vision that is followed by the alterations in the vision field. Most frequent symptom of the illness is increased pressure in the eye. Glaucoma is one of the main causes of blindness. This disease is usually observed for patients after 35 years of age. But discovered in due time loss of vision caused by glaucoma can be almost always prevented.
Usually eye drops decreasing pressure in the eye or helping the liquid to absorb or eliminating amount of liquid that flows into the eye are used for the treatment and observation of glaucoma. To achieve good results medications should be used regularly and uninterruptedly. By following changes in the development of glaucoma it is possible to change medications in due time. Damages caused by glaucoma can’t be prevented but eye drops, capsules, as well as surgery prevent chances of further damages and allow retaining vision.
If you do not tolerate medications, or medications are not capable of reducing pressure in the eye, then surgery is needed. Sometimes it is enough to apply laser treatment but sometimes also surgical intervention is necessary to create the drainage channel. Still in these cases the recommended surgery is much safer and effective measure for retaining of the vision than to give glaucoma a possibility to develop and irreversibly harm the vision nerve.
Task of the corneal – fibred, transparent front part of the eye that covers optical systems of the eye – is to protect eyes from mechanical damages and infections. Similarly as task of the wrist watch is to protect a clock-face. When glass breaks, it needs to be changed. Unfortunately also corneal is not immune from damages. Most often damages are caused by keratitis that is the inflammation of the corneal of the eye and cause of ulcers. Due to keratitis corneal is becoming hazy and haziness increases with the cicatrisation to such extent that it does not let light to pass through. Also ulcers can damage corneal to such extent that it needs to be replaced. With the so-called “emergency method” doctors try to perform application of contact lenses but it does not always help. Also genetically determined progressive dystrophy of tissues can be encountered pretty often but in these cases the sick corneal usually can’t be cured with medications and then corneal transplantation is required. Corneal can become hazy also after cataract or other eye surgeries, especially, if the tissues of the patient’s eye turned out to be fragile and not solid. The hazier the cataract is, the greater is the risk that corneal can suffer due to surgery.
Now our clinic provides possibility to perform two methods of corneal transplantations – the full corneal transplantation that is known for a long-time and widely used around the world (during this procedure all five layers of the corneal are transplanted, without separating them), or the new method – keratoplasty of the inner part of corneal DMEK that is the Descement’s Membrane Endothelial Keratoplasty. DMEK is used if the inner layer of corneal is damaged. It should be pointed out that its density is four microns (for comparison – density of the central part of corneal is from 450 to 600 microns).
DMEK surgery had very good results, also rehabilitation period of the patient were much shorter than after the full transplantation of the corneal when, for example, stitches can be removed only year after surgery. After DMEK there are no stitches at all, also structure of the eye is not altered and improvement can be observed already within a week. As the optical system of the eye is not affected during this surgery, then the short-sightedness or farsightedness of the person remains the same. It is important to note that when only membrane is transplanted (DMEK), it is usually not rejected. Surgery is performed under local anaesthesia and lasts approximately an hour. If at the same time patient undergoes also cataract surgery, then it lasts longer.
Necessary transplants are provided in cooperation with the live tissue bank in the United States of America.
High-Definition Vision Correction with implantation of Intraocular Collamer Lens (ICL) – the treatment of refractive surgery to correct short-slightness, long-sightedness and astigmatism, let forget about glasses and contact lens forever.
ICL is made from a special material - collamer - and the lens is inserted through a 3 mm hole in the eye between the iris and the eye lens. And it can stay in the eye permanently. It does not need any special care. It cannot be seen and the patient feels no physical discomfort. ICL is made for long term or permanent use but it is possible to remove it because the lens does not change the tissues of the eye or the cornea. If you are very short or long-sighted this can be corrected by ICL. It can also help if you have a thin cornea, dry eyes or large pupils.
The advantages of this operation are that it does not make any irreversible change to the cornea of the eye and patients recover very quickly. You will feel some improvement in your eyesight in only a matter of hours after the operation.
Usually surgery is performed under local anesthetic.
If your child has an eye problem, is having difficulty with a vision screening exam or has difficulty reading or learning, or needs surgery or medical treatment for an illness affecting the eyes, a pediatric ophthalmologist has the experience and qualifications to treat your child.
One of the pathologies harming coordinated action of the eye is strabismus. Usually in this case other people notice constant or period asymmetry of the condition of the eye. Patient is disturbed by the doubling, he looses ability to perceive objects stereoscopically, perceive depth, frequently also acuity of vision is reduced in the eye having heterotropia and it causes orientation disorders in the environment. It should be understood that non-symmetric action of the eye is pathologic and will not go away with age.
Moment of performance of the surgery depends on the fact how much strabismus impact life of the patient. With help of the surgery it is possible to achieve significant visual improvement of the appearance of the eye. To achieve this maybe even several surgeries will be needed. In case if not only visual appearance is improved but also cooperation between both eyes, surgery should be carried out as fast as possible.
Surgery does not help to improve poor vision; therefore covering of the eye could be also needed after the surgery. Also wearing glasses would not be beneficial as surgery does not correct short-sightedness or farsightedness.
