Presbyopia treatment with Trifocal Smart Lens Implantation
Presbyopia is a common age-related condition that affects people over 40, causing a reduction in the flexibility of the eye lens and making it difficult to perform daily tasks at a distance of 35 to 40 cm. This includes activities such as reading, using a mobile phone or doing intricate work. The most common solution to this problem is to wear prescription glasses.
Fortunately, there are several methods available to treat presbyopia, including glasses, contact lenses, laser surgery, and intraocular lens implants. A relatively new and advanced treatment option for presbyopia is Trifocal/Multifocal Smart Lens Implantation. This procedure involves implanting a special lens in the eye that allows the patient to see objects clearly at all distances, without the need for glasses or other devices. Additionally, this treatment significantly reduces the risk of developing cataracts later in life.
Trifocal/Multifocal Smart Lens Implantation is performed on an outpatient basis, using advanced laser technology and precise computer and ultrasonographic calculations. The entire procedure typically takes no more than two to three hours.
Eye pressure or GLAUCOMA and treatment methods
What is Glaucoma?
Our eye as a closed space is almost the size of a ping pong ball, and in order to maintain its shape, on the one hand, aqueous humor is continuously secreted inside the eye, and on the other hand, this liquid is released through very special exit ways from The eye goes out. If, for any reason, the exit ways of the aqueous humor are narrowed, this will increase the aqueous humor in the eye and ultimately increase the intraocular pressure, and this increase due to the great pressure it exerts on the blood vessels feeding the eye causes the string the optic nerve gradually disappears and the longer the disease starts, the more the eye nerve cells die, and the person loses their peripheral vision to the same extent.
Glaucoma is a dangerous disease and if it is not diagnosed and treated in time, it will eventually lead to total blindness. The reason for the dangerousness of this disease lies in the fact that it does not show any symptoms for many years after the onset of the disease and the affected person is not aware of his disease. Second, after diagnosis, the amount of vision that has been lost cannot be recovered in any way.
Glaucoma treatment methods:
Preventing this disease is completely possible. That's why it's recommended to undergo regular examinations and checks, especially for individuals over the age of 40, in order to detect and manage glaucoma early on.
The disease can be treated with eye drops that help reduce aqueous humor, which should be used continuously throughout the person's life after starting. Additionally, specialized lasers (SLT) can also be used as a treatment method.
If the eye pressure cannot be controlled with the above treatments, surgical procedures such as trabeculectomy and shunt implantation (such as the Ahmad valve) can be performed. Rest assured that all of these treatment options are available at our clinic.
Cataract and treatment
As human beings, we are born with a natural, strong lens inside our eyes that allows us to see clearly. However, this lens may lose its transparency and become cloudy, leading to a condition known as cataracts. Cataracts are most commonly caused by aging, with most people experiencing this condition at the age of 50 and above. Additionally, cataracts can be caused by other factors such as diabetes, eye trauma, certain medications, and systemic diseases. In some cases, a person may be born with congenital cataracts, which requires immediate surgery. Unfortunately, there is no medical treatment to cure cataracts, and the only solution is surgery. During the surgery, the cataract is removed, and an intraocular lens is implanted in its place to restore clear vision.
In the normal state, tears are secreted by various secretory glands that are located in the white of the eyes as well as the upper and lower eyelids and create a transparent, smooth, moist and slippery surface on the surface of the cornea. The secretion of tears continues continuously and uniformly, and these tears, after completing their mission, flow through the very fine tear ducts located in the corners of the upper and lower eyelids into the lacrimal sac and from there into the nasal cavity. If the lacrimal ducts are closed due to a reason such as infection or trauma, it will no longer be able to drain the tears secreted in the eye, and these tears will inevitably flow down the person's face and cheeks. In addition to disrupting the visual system, this will cause other problems such as eye infections and lowering the quality of life of the affected person.
Lately, open surgical methods have been used to treat this complication, which has a low chance of success. Currently, this operation can be performed by multi-diode laser and with local anesthesia on an outpatient basis and with a very high success rate. This type of laser operation is also available in our clinic and many patients are treated in this way.
The treatment of refractive errors in the eye.
Refractive errors are vision problems that occur when the eye's light does not focus correctly on the retina. There are four types of refractive errors, namely myopia, hyperopia, astigmatism, and presbyopia. Fortunately, there are several ways to correct these errors. One of the most popular methods is laser correction, which is used to treat farsightedness, myopia, and astigmatism. This treatment involves changing the shape of the cornea using the excimer laser to ensure the proper focus of the light. The available laser correction methods include LASIK, PRK, Trans PRK, Femto LASIK, and Femto Smile, which are selected based on the type of eye, the degree of weakness, and the consultation with an expert doctor.
Treatment for Strabismus and Ambliyopia (lazy Eye)
Lazy eye, also known as ambliyopia, is a common and important disease that affects infants and children. It occurs when an eye does not have any specific or organic disease, yet it lacks sufficient vision. Babies have very little vision at birth and gradually learn to see as the cells responsible for vision in the retina are stimulated by light. If the focus of light on the retina is not correct due to reasons such as drooping eyelids, corneal opacities, cataracts, congenital glaucoma, retinal problems, strabismus, or refractive errors, the eye may remain lazy.
Refractive errors, which cause weakness in the eyes, are particularly important but may not be visible to the naked eye.
Strabismus or squint is another condition that can cause lazy eye. In normal situations, the visual axis of both eyes is aligned and both eyes look at a common point at the same time. This causes two different images to be sent to the vision centers in our brain, which combines them to create a three-dimensional image and depth perception. However, if the eyes are not aligned, one of the eyes looks in a different direction, which is known as strabismus or squint. This condition may deviate the eye to four directions: up, down, left, or right. In children, the brain may ignore the image transmitted from the deviated eye, which can cause lack of normal development and eventually lead to lazy eye. In adults, strabismus causes double vision, which is a very uncomfortable condition that requires urgent investigation and treatment.
Keratoconus and treatment methods
The cornea of the eye normally has an hourglass shape and protrudes slightly outward. The colored part of the eye, called the iris, is located at the front of the cornea. When we touch our eye, we touch the cornea directly. The shape of the cornea doesn't usually change throughout our lifetime. However, in people with keratoconus, the curvature of the cornea starts to increase during puberty and continues to do so until around the age of 35-40. This causes the cornea to protrude and gradually take on a cone shape, instead of remaining spherical. As the disease progresses, irregular astigmatisms develop that cannot be corrected with glasses. This leads to severe vision loss in the affected eye. Patients with keratoconus may change their glasses frequently, but their vision doesn't improve. As the cornea becomes more conical, it also becomes thinner, and in some cases, it can even be pierced, leading to total vision loss.
There are more ways to stop the progression of keratoconus than to treat it. The most effective way to stop the disease from progressing is to undergo a cross-link operation. During this procedure, a special type of ultraviolet rays, along with riboflavin, is applied to the cornea. This increases the strength of the collagen fibers in the corneal tissue, preventing the cornea from becoming deformed. Our center offers this procedure, which has been successful in treating many patients.
Corneal transplantation
Corneal transplant is a surgical procedure that involves replacing one or more layers of the cornea, which is the transparent front part of the eye. The cornea has five layers, and depending on the disease or condition affecting it, one or more layers may need to be replaced to restore vision. Some of the conditions that may require a corneal transplant include advanced keratoconus, hereditary corneal opacities, corneal opacities caused by infections, and age-related problems affecting the inner layer (endothelium) of the cornea. Corneal transplant may also be necessary to address opacity and swelling of the cornea resulting from previous surgeries or injuries.
What is corneal opacity?
Cornea is the transparent layer in front of the eye, which forms an important part of the optical and visual system of the eye. The presence of any spot on the cornea reduces its transparency, prevents light from reaching the retina to different degrees, and this causes a decrease in vision, which in some cases requires a corneal transplant to treat this problem.
Keratoconus is a condition that causes irregular astigmatism in the eye due to changes in the curvature of the cornea, which can be caused by factors such as heredity and genetics. In severe cases, glasses may not be enough to correct the vision, and individuals may need to use hard contact lenses or undergo corneal cross-linking (CCL) treatment. If vision does not improve or complications arise, corneal transplant surgery may be necessary.
There are different types of corneal transplants depending on the type of lesion. Penetrating transplant or full corneal layer (PKP), layered transplant (DLK), and endothelium layer transplant or DSAEK are some examples. For keratoconus or keratoconus-related conditions, DLK layer grafting is typically used. This is because in keratoconus, the front layers of the cornea are damaged, and there is no need to replace the inner layer, which reduces the chance of transplant rejection.
The cornea for transplant is obtained from a donor's body, and since a healthy cornea does not have any blood vessels, the chance of rejection is lower compared to other body parts. Additionally, the chance of layer connection failure is also minimal.
