Glaucoma: Eye Pressure: Glaucoma

What is Glaucoma?

Glaucoma is an insidious disease which may progress to loss of vision if not diagnosed and treated at an early stage. Therefore, eye pressure should be controlled with regular yearly eye examinations.

Glaucoma means a set of conditions that damage the optic nerves. The main cause of glaucoma is increased pressure inside the eye. The optic nerve can become more sensitive to pressure if circulation of the optic nerve is compromised and tissue weakness or structural disorders develop, and damage can occur without increase in pressure.

Glaucoma Treatments

There are three main methods in the treatment of glaucoma:

  • Drug therapy
  • Surgical treatment
  • Laser treatment

Eye curtain: Cataract

What is Cataract?

Cataract is the clouding of the eye's natural lens. This lens, which is present in the eye at birth, is made of protein and water. The special arrangement of proteins ensures that the lens stays clean and light is able to pass through. As years pass, small protein molecules start to clump and as a result the lens becomes clouded. Mature cataract develops when this clouding expands and covers the entire lens, preventing the passage of light.

Symptoms of Cataract

When it loses its transparency, the lens becomes like a smoky, frosted or stained glass and visual complaints arise. Objects seem shapeless, blurred or erased. There is eye fatigue and headache. These are the main cataract symptoms.

Cataract Treatment

Cataract cannot be treated with drugs so surgical treatment is the solution.In a cataract surgery, the clouded, opacified lens is removed and replaced with an artificial lens, recovering the patient's good vision. If blurred vision hinders the patient's routine activities (difficulty in reading, watching TV, driving), the decision of surgery is made by specialist doctors based on the patient's needs. At Dünyagöz Hospital, cataract surgeries are performed by a team of specialist doctors who are experienced in this field.

In cataract treatment, medical therapies such as drugs or eye drops, exercise or spectacles do not solve the problem. The only treatment for cataract involves replacing the eye's cataractic lens with a clear intraocular lens. The likelihood of success is very high in cataract surgeries.

If your doctor tells you that cataract has started to develop in your eyes, the right time for surgery may come years later. Your vision may improve with a new pair of prescription glasses. Magnifying lenses or strong light can make your daily routine easier. If your cataract affects your daily life and makes activities like reading and driving difficult, you don't have to live with it.

Cataract can only be treated with surgery. However, the answer to the question "When should a patient have cataract surgery?" depends on the technique to be used in surgery. At Dünyagöz hospitals, cataract surgeries are performed using the latest method available in the world, which is the PHACO (phacoemulsification) technique.

Corneal Coning: Keratoconus

What is Keratoconus?

Keratoconus is an eye condition in which the transparent outermost layer of the eye, the dome-shaped cornea, progressively thins causing a cone-like bulge to develop.

The onset of corneal coning is usually in puberty, but patients become aware of the condition in their 20s. Corneal coning progresses slowly between the ages of 20 to 40 and becomes stable after 40. Today, this condition affects one in every 2,000 people in Western societies. The prevalence of keratoconus is increasing each year. Corneal coning, the symptoms of which include progressing myopia and astigmatism and the thinning and cone-like bulging of the cornea, can be diagnosed at an early stage using special testing methods.

Keratoconus is a disease which requires specialist expertise and monitoring. An experienced team should be combined with state-of-the-art technology for diagnosis and treatment of the disease. Dünyagöz hospitals have a dedicated Keratoconus Diagnosis and Treatment Center for the treatment of corneal coning.

Treatment Methods for Keratoconus:

Contact Lenses
The first tool to increase visual quality in patients with corneal coning is a pair of glasses. However, glasses may not provide clear vision in patients with keratoconus since the problem concerns deformity of the cornea. Therefore, gas-permeable lenses are used to increase visual quality and have clearer vision.

Intraocular Ring Treatment: Intacs
When Intacs rings are inserted into the corneal tissue, they flatten the cornea and eliminate the coning/bulging of the cornea which is caused by keratoconus. Myopia is also corrected with this procedure.

Think of the eye as a tent with a round top which looks like the cornea.

The Intacs ring implanted in the eye is clear and made of a material which is compatible with ocular tissue, without causing any problems in its lifetime, and can also be removed when necessary. It cannot be seen from the outside after the surgery and its presence in the eye cannot be felt either.

Crosslinking therapy first started to be used at our hospital in March 2006 and has been implemented successfully in more than 2000 patients as of today. UV-Cross Linking surgery can stop the progression of corneal coning by using UVA light and Riboflavin to impact the collagen molecules of the cornea, thus enhancing corneal biomechanics. This treatment started to be provided at Dünyagöz Hospital concurrently with other centers all over the world.

Corneal Transplant
Should keratoconus be at the latest stage with highly reduced vision and the patient cannot benefit either from contact lenses or intrastromal corneal rings, the only treatment option that remains is corneal transplant. Corneal transplantation, commonly known by the public as an eye transplant, is in fact a surgical procedure where only the cornea that is distorted due to various diseases is replaced with a donated cornea. In corneal transplant surgery, a circular piece with a diameter of 6-9 mm is excised from the healthy donor cornea; a piece of the same diameter is also extracted from the recipient (patient) cornea and the healthy piece is then sutured into this opening. The surgery is preferably done under general anesthesia.

Eye machining:Excimer Laser Therapies

Eye machining is a treatment option for people with problems such as myopia, hyperopia and astigmatism. Excimer Lasertreatment has been recognized in the medical community as a reliable method with known regulations and results. Since the early 1980s, millions of people have benefitted from this treatment and were relieved of the limitations of wearing glasses or contact lenses that they encountered in their social and professional life.

Night Blindness: Retinitis Pigmentosa

What is Night Blindness:
A congenital disease of the retina, night blindness cannot be treated with medication or with surgery today. It is more likely to occur in people with kin marriage in the family. Cell transplant studies for the treatment of night blindness may provide a solution in the future. Stem cell and genetic treatment options are available for retinal diseases.

Dog's elbow: Sty

Colloquially named a "dog's elbow", sty is termed as "Hordeolum" by doctors. A pus-filled bump develops in the lash line. There is pain and throbbing. The patient should avoid touching the sty and consult a specialist ophthalmologist. Sty can be treated with medication or surgery. The doctor determines the suitable treatment method for the patient after an examination.

Eye Transplant: Corneal Transplant

Corneal transplant, colloquially called an "eye transplant", is in fact a surgical procedure where the clear, outer layer of the eye that is distorted due to various diseases is replaced with healthy cornea tissue recovered from a deceased person. In corneal transplant surgery, a circular piece with a diameter of 6–9 mm is excised from the healthy donor cornea. A piece of the same diameter is also extracted from the recipient's (patient's) cornea and the healthy piece is then sutured into this opening. With advancing technology, corneal surgeries can now be performed using the Intralase Laser technology. In this operation, the cornea's affected layer is cut with Laser. The eye's intact areas are not harmed. Similarly, a new and intact corneal layer is cut by Laser, according to the needs of the recipient's eye, and implanted in the eye. In Intralase corneal transplants (Intralase Keratoplasty), the greatest advantage of the ability to distinguish between healthy and sick tissue is that there is almost no rejection of the transplant.
