Recommended cornea specialists

What does a cornea specialist do?

If you face visual problems related to the cornea or wish to prevent serious eye diseases, a cornea specialist is the most suitable professional. This ophthalmologist has specific training to diagnose and treat all pathologies that affect this transparent and fundamental layer of the eye, offering modern and effective solutions to preserve and restore your vision.

Different from a general ophthalmologist, the cornea specialist possesses deep knowledge in cellular biology, infectology, optical physics, and ocular biomechanics. Their expertise allows them to perform from conservative treatments to complex surgical procedures, such as corneal transplants and innovative corneal strengthening techniques. All treatments are personalized according to each patient's specific condition, always prioritizing maximum preservation of visual function.

Anatomy and function of the cornea

To understand the importance of the cornea specialist, it is fundamental to know the structure and function of this vital part of the eye. The cornea is composed of five distinct layers, each with specific functions that contribute to transparency and structural resistance.

The epithelium represents the outermost layer, functioning as a protective barrier against external agents and minor trauma. Bowman's membrane offers structural support and resistance, while the stroma, which represents approximately 90% of the cornea's thickness, determines its transparency and mechanical resistance. Descemet's membrane acts as a thin layer that separates the stroma from the endothelium, and finally, the endothelium is responsible for regulating corneal hydration, maintaining its transparency through active fluid pumping.

The cornea plays a fundamental role in vision, being responsible for approximately 65% of the eye's refractive power. Its perfect transparency is essential for the formation of sharp images on the retina, and any alteration in its structure can significantly compromise visual quality.

When to seek a cornea specialist?

Various signs and conditions indicate the need to seek a cornea specialist. Recognizing these symptoms early can make the difference between conservative treatments and more complex interventions.

Keratoconus and curvature alterations

Keratoconus represents one of the main causes of corneal transplants in Brazil, manifesting mainly between 10 and 25 years of age. If you notice frequent changes in your glasses prescription, blurred vision that doesn't improve with optical correction, image distortion, or photophobia, you may be developing this condition. Early diagnosis allows for less invasive treatments like corneal crosslinking, avoiding disease progression and achieving more satisfactory results.

Infections and corneal ulcers

Intense eye pain, significant redness, purulent discharge, and sudden vision decrease may indicate serious corneal infections, such as bacterial, fungal, or viral keratitis. These situations constitute ophthalmological emergencies that require urgent specialized treatment to avoid permanent sequelae, corneal perforation, and preserve tissue transparency.

Severe dry eye syndrome

When dry eye symptoms don't respond to conventional treatments with artificial tears, a cornea specialist can identify specific causes such as Meibomian gland dysfunction, Sjögren's syndrome, or vitamin A deficiencies. Severe dry eye syndrome can lead to corneal complications like punctate keratitis, ulcers, and scars if not adequately treated.

Eye trauma

Accidents that affect the cornea, including cuts, perforations, chemical or thermal burns, require immediate specialized evaluation. The cornea specialist possesses the necessary techniques to repair this damage through specialized sutures, biological adhesives, or reconstructive procedures, minimizing scars and preserving visual function.

Family history of corneal diseases

A family history of corneal diseases, such as hereditary Fuchs' dystrophies, keratoconus, or other genetic conditions, indicates the need for preventive monitoring. The specialist can detect early changes through specific examinations and guide preventive measures or timely treatments before symptoms manifest.

Main treatments offered

Currently available treatments range from drug therapies to highly complex surgical procedures, always prioritizing less invasive techniques when possible.

Corneal crosslinking

Crosslinking is a medical procedure that reinforces the cornea's structure through the creation of cross-links between collagen fibers. It uses a combination of riboflavin (vitamin B2) and ultraviolet light applied to the corneal surface after epithelium removal. This modern treatment is highly effective in stopping the progression of keratoconus and other corneal ectasias, representing a safe alternative to transplantation in initial and moderate cases.

Intracorneal ring implant

Intracorneal rings, also known as Ferrara rings, are semicircular devices made of biocompatible material that regularize corneal curvature when glasses and contact lenses no longer provide adequate visual correction. This minimally invasive procedure is performed through tunnels created in the corneal stroma, being able to significantly delay or avoid the need for transplantation in many cases of keratoconus and irregular astigmatism.

Corneal transplant

When other treatments are not viable or effective, corneal transplantation remains as a definitive option to restore vision. Modern techniques include anterior and posterior lamellar transplants that preserve healthy layers of the patient's cornea, providing faster recovery, lower rejection risks, and better final visual quality. Full penetrating transplantation is still performed in more severe cases with involvement of all corneal layers.

Advanced treatments for dry eye

Advanced therapies include the use of autologous serum rich in growth factors, lacrimal plug implantation to conserve natural tears, Meibomian gland treatment through massage and heating, specific anti-inflammatory medications like cyclosporine and tacrolimus, plus intense pulsed light therapies. The specialist identifies specific causes of dry eye syndrome and personalizes treatment combining different therapeutic modalities.

Modern diagnostic methods

The cornea specialist uses state-of-the-art equipment for precise diagnosis and evolutionary monitoring of corneal diseases. Computerized corneal topography maps anterior and posterior curvature in detail, allowing early detection of alterations like keratoconus and irregular astigmatism.

Anterior segment optical coherence tomography provides high-resolution images of corneal layers, measuring thicknesses with micrometric precision and detecting subtle structural alterations. Specular microscopy evaluates the health and density of endothelial cells, fundamental for maintaining corneal transparency.

Ultrasonic biomicroscopy allows detailed evaluation of corneal anatomy in cases of opacification, while aberrometry analyzes optical distortions caused by surface irregularities. These examinations allow precise monitoring of disease evolution and guide therapeutic decisions based on objective evidence, enabling treatment adjustments and early detection of complications.

Advantages of consulting a specialist

Seeking a cornea specialist offers significant benefits for preservation and restoration of visual health through highly specialized care.

Precise and early diagnosis

Specialized knowledge allows precise identification of corneal pathologies in initial stages, when therapeutic options are more conservative and results more favorable. This can prevent progression of diseases like keratoconus, dystrophies, and infections, reducing the need for more complex and invasive treatments in the future.

Access to innovative treatments

Specialists constantly stay updated with the latest therapeutic innovations and possess experience with modern techniques like corneal crosslinking, lamellar transplants, regenerative therapies with stem cells, and personalized treatments for dry eye syndrome. This guarantees access to the best and most effective treatments available in current medicine.

Preservation of visual function

The main objective is always to preserve or restore the best possible vision through individualized approaches. Through personalized treatments and regular specialized monitoring, many conditions that previously led to significant visual loss can now be effectively controlled, maintaining quality of life and visual independence.

Prevention of complications

Specialized management significantly reduces the risks of serious complications like corneal perforation in infections, uncontrolled keratoconus progression, transplant failure, or development of scars that compromise vision. Regular and protocol-based monitoring allows timely interventions when necessary, avoiding irreversible deterioration.

How to choose the ideal specialist

Selecting the appropriate cornea specialist is fundamental to guarantee the best therapeutic results and a satisfactory care experience. Some important criteria should guide your choice to ensure quality and safety in treatment.
