A step towards a clear vision with Dr. Mehran Zarei Qanawati
Keratoconus, or keratoconus, is one of the complex and progressive eye diseases that can gradually reduce the quality of people’s vision and cause serious vision challenges. With the advanceme of medical science and new technologies, several treatmes have been provided to corol and even restore the damaged cornea, which have given many hopes to paties in this field. Corneal transpla, as one of the effective solutions in the advanced stages of this disease, has been able to create a great transformation in improving the vision and quality of life of paties. We are looking to iroduce new methods for the treatme of keratoconus. We will also get to know Dr. Mehran Zarei Kanavati, cornea specialist and professor at Tehran University of Medical Sciences, who has high experience and knowledge in eye surgeries such as correction of refractive errors, cataracts, and advanced corneal transpla techniques, including stem cell transplas and artificial corneas, and is considered a reliable reference in this field. The purpose of this article is to raise awareness about keratoconus disease and provide complete information about the treatme of keratoconus and its latest treatme methods. This article examines the causes, symptoms, and rece treatme advances to provide a clearer perspective to paties and their families, and to answer frequely asked questions about the cost of corneal transplas.
Corneal hump what is it Comprehensive understanding of an eye disease
Keratoconus, medically known as keratoconus, is a progressive eye disease in which the cornea, the clear, dome-shaped part at the fro of the eye, gradually thins and takes on a conical or humped appearance instead of its normal spherical shape. This deformation in the cornea does not focus the light rays eering the eye properly and as a result leads to blurred vision, sensitivity to light and seeing halos around light sources. This condition can occur in one or both eyes and usually begins during adolescence or early tweies.
Early detection of keratoconus is very importa, because with the progression of the disease, the vision problems worsen and the options Treatme of keratoconus They become more limited. The prevalence of this disease varies in differe populations, but it affects about 1 in 2,000 people. Recognizing the early symptoms and visiting an ophthalmologist for regular examinations can help maiain the quality of vision and manage the disease more effectively.
Causes and risk factors: Why does keratoconus occur?
Keratoconus is a progressive disease in which the cornea of the eye gradually thins and becomes conical. Understanding the causes and risk factors of this disease is vital for its preveion and timely diagnosis. One of the most importa factors is genetic predisposition; Although keratoconus does not always have a clear inheritance pattern, family history is observed in about 10% of cases, which indicates the role of genes in its occurrence.
Iense and chronic eye rubbing is also considered one of the key risk factors. This action can damage the delicate tissues of the cornea and accelerate its thinning process. In addition, certain underlying diseases such as Down syndrome, Ehlers-Danlos syndrome, and retinitis pigmeosa are associated with an increased risk of developing keratoconus. Eye allergies and chronic inflammation of the eye can also indirectly coribute to the developme of the disease by stimulating the person to rub the eye. Certain environmeal factors and even long-term use of inappropriate coact lenses have also been studied as facilitating factors. Ideifying these factors helps doctors in providing suitable treatme solutions for keratoconus.
Signs and symptoms of keratoconus: early diagnosis for effective treatme
Early diagnosis Corneal hump To begin with Treatme of keratoconus And effective disease manageme is critical. The disease usually begins with relatively mild initial symptoms that gradually progress. Early symptoms include increasing blurring of vision that is not fully corrected with regular glasses or coact lenses. People may experience diplopia, especially when looking at dista objects. Sensitivity to light (photophobia) and seeing halos around light sources, especially at night, are other common symptoms.
with progress Corneal humpThese symptoms are aggravated and the quality of the person’s vision is severely affected. For accurate diagnosis, ophthalmologists use differe methods. One of the most importa and advanced diagnostic tools is corneal topography. This method, by creating a precise map of the corneal surface, detects the smallest changes in curvature and its characteristic irregularities. Corneal hump is, ideifies Other investigations including pachymetry (measureme of corneal thickness) and abiometry also help to complete the diagnosis. Timely detection of the possibility of planning for Treatme of keratoconus provides and may require more advanced measures such as Corneal transpla delay or even preve it in the early stages.
New approaches to treatme of keratoconus: from stabilization to restoration of vision
With significa advances in ophthalmology, Treatme of keratoconus It has eered a new phase, the goal of which is not only to stabilize the progress of the disease, but also to restore and significaly improve the vision of paties. These new approaches include a wide range of options, ranging from minimally invasive procedures to advanced surgeries. in the past, Corneal hump It often resulted in severe vision loss, but today, with modern techniques, life expectancy with quality vision has increased for paties. Methods such as cross-linking to stabilize the cornea and in more advanced cases, options such as Corneal transpla It is suggested that each one has its own advaages and their choice depends on the severity and progress of the disease.
Cross-linking: stopping the progression of the disease
Crosslinking is one of the first and most importa new methods in the treatme of keratoconus, which aims to stop the progression of this disease. The mechanism of action of this method is that eye drops coaining vitamin B2 (riboflavin) are first dripped on the cornea. Then, by irradiating ultraviolet rays (UVA) to the cornea, riboflavin is activated and causes the creation of new cross-links between the collagen fibers of the cornea. This process helps to strengthen the corneal tissue and increase its strength, thereby preveing its further thinning and deformation.
Good candidates for crosslinking are usually young people whose keratoconus is progressing and whose corneas have not yet thinned severely. The expected results of this treatme are stabilizing the condition of the cornea and preveing further deterioration of vision. In many cases, crosslinking effectively halts the progression of keratoconus and can delay or eliminate the need for more invasive procedures such as corneal transplaation.
Iracorneal rings (ICRS): improveme of corneal shape and vision
Iracorneal rings (ICRS), as an advanced approach in the treatme of keratoconus, play an importa role in changing the shape and improving the function of the cornea. This method involves placing two small semicircular pieces of transpare polymer material in the middle layers of the cornea. The main purpose of these rings is to restore the natural curvature of the cornea and reduce the bulge caused by keratoconus, which in turn helps to regularize the surface of the cornea and reduce irregular astigmatism.
With ICRS implaation, the pressure is redistributed around the ceer of the cornea, making the ceral part smoother. This structural change, in addition to improving the overall shape of the cornea, directly increases the quality of vision by reducing distortions and blurred vision. Iacs are often recommended for paties whose keratoconus is not very advanced and has not yet reached the stage of corneal transplaation, and can improve the patie’s vision and reduce the need for hard coact lenses. This method is one of the effective options for maiaining and improving vision in paties with keratoconus.
Iraocular lenses Advanced: A vision correction solution
After completing the initial stages of keratoconus treatme, some paties may still have residual refractive errors that make it difficult to achieve the best quality of vision. These lenses are usually suitable for people who have good vision with glasses. Advanced iraocular lenses are considered a new solution to complete the treatme process of keratoconus and the final improveme of vision. These lenses are implaed in the eye with high precision and are able to effectively correct residual astigmatism, nearsightedness or farsightedness that may be prese even after procedures such as corneal transplaation. The goal of using these lenses is to help paties achieve clearer vision and reduce dependence on glasses or coact lenses, which significaly affects their quality of life.
Corneal transpla: The latest solution and new techniques with the expertise of Dr. Zarei Qanawati
In cases where the keratoconus disease has reached advanced stages and other treatme methods such as glasses, special coact lenses, or cross-linking are no longer able to improve vision, corneal transplaation is proposed as the last and most effective solution. This complex surgery aims to replace the damaged cornea with a healthy donor tissue so that the patie can regain his sight and improve his quality of life.
Modern corneal grafting techniques have made significa advances and are no longer limited to full-thickness (PK) grafting. Today, methods such as deep aerior lamina grafting (DALK), which replaces only the damaged layers of the cornea and preserves the patie’s healthy inner layer, are preferred due to the reduced risk of transpla rejection and accelerated recovery. Usually, people with keratoconus do not need corneal stem cell transplaation or artificial corneas.
Choosing the right technique and its precise implemeation requires the expertise and experience of the surgeon. Dr. Mehran Zarei Qanawati, with years of experience and skill in the field of eye surgery and especially corneal transpla, is considered one of the pioneers of using new techniques in Iran. By applying advanced methods that are also used in iernational reputable ceers, they have achieved successful results in the treatme of paties with advanced keratoconus. Paying atteion to the details and expertise of the surgeon is vital at this stage; Because the success of the cornea transpla and the quality of the patie’s final vision are directly depende on the skill and knowledge of the surgical team. Along with the medical aspects, considering the various aspects of the surgery, including the cost of the corneal transpla, is one of the things that paties should consult with their doctor.
Corneal transpla costs and factors affecting it
Corneal transplaation, which is one of the effective methods of “curing keratoconus” in advanced stages of the disease, requires consideration of its financial aspects. “Cornea transpla cost” can be affected by several factors. The selected treatme ceer will affect the “cost of cornea transpla”. Insurance coverage for this type of surgery also varies depending on the type of insurance and its conditions and can cover a significa part of the costs.
Preveion and manageme: recommendations for maiaining eye health
To preve the exacerbation of keratoconus and to effectively manage it, it is necessary to follow key recommendations. The most importa step is to strictly avoid rubbing the eye, as this can damage the weak corneal tissue and accelerate the progression of keratoconus. Regular eye examinations, at least once a year, are vital for early detection of changes and proper planning of keratoconus treatme. In these examinations, the specialist can provide preveive and therapeutic solutions, including options to preve the need for a cornea transpla in the future, by carefully examining the condition of the cornea. Observance of these things is complemeary to the treatme of keratoconus and helps to maiain eye health and vision.
Conclusion: A look at a bright future with modern ophthalmology
In general, keratoconus is a progressive eye disease that can be corolled and vision preserved with early diagnosis and the use of modern treatmes. It is very importa to refer to experienced specialists to carefully check the symptoms and choose the best treatme method for keratoconus. Significa advances in the field of ophthalmology, including new methods of corneal stabilization and corneal transplaation, have brought hope for a brighter future and improved quality of life for paties with keratoconus. These approaches promise to restore vision and ensure eye health.
