The cornea is a transparent, dome-shaped tissue that covers the front of the eye, playing a crucial role in focusing light and maintaining clear vision. However, when the cornea becomes infected, it can lead to significant discomfort and vision impairment. Corneal infections, also known as keratitis, can be caused by bacteria, viruses, fungi, or parasites, and prompt treatment is essential to prevent complications and preserve vision. At SightMD, we’re dedicated to providing comprehensive care for corneal infections, offering effective treatment options tailored to each patient’s needs.

1. Antibiotic Eye Drops: In cases of bacterial keratitis, antibiotic eye drops are typically the first line of treatment. These medicated drops work to eliminate the infection-causing bacteria and reduce inflammation in the cornea. Depending on the severity of the infection, your ophthalmologist may prescribe broad-spectrum or specific antibiotics to target the underlying cause effectively. It’s crucial to use antibiotic eye drops as directed and complete the full course of treatment to ensure the infection is fully eradicated.
2. Antifungal Medications: For fungal keratitis, antifungal medications such as antifungal eye drops or oral antifungal agents may be prescribed. These medications work to inhibit the growth and spread of the fungal infection within the cornea. In severe cases, your ophthalmologist may recommend a combination of topical and systemic antifungal therapy to achieve optimal results. Close monitoring and regular follow-up appointments are essential to assess treatment efficacy and prevent recurrence of the infection.
3. Antiviral Medications: In cases of viral keratitis, antiviral medications are used to suppress viral replication and reduce inflammation in the cornea. Depending on the specific virus involved, your ophthalmologist may prescribe topical antiviral eye drops, oral antiviral medications, or a combination of both. While antiviral medications can help manage the symptoms of viral keratitis, they may not fully eliminate the virus, and recurrence is possible. Regular follow-up appointments and ongoing monitoring are essential to manage the condition effectively.
4. Corticosteroid Eye Drops: In some cases of corneal infection, corticosteroid eye drops may be prescribed to reduce inflammation and promote healing in the cornea. However, corticosteroids are typically used in combination with antimicrobial medications and under close supervision by your ophthalmologist. Prolonged or inappropriate use of corticosteroids can exacerbate the infection and lead to complications, so it’s essential to follow your doctor’s instructions carefully.
5. Corneal Debridement or Surgery: In severe cases of corneal infection that do not respond to conservative treatment measures, surgical intervention may be necessary. Corneal debridement, or the removal of infected tissue from the cornea, may be performed to eliminate the source of the infection and promote healing. In advanced cases or when vision is significantly compromised, corneal transplantation surgery may be recommended to replace the damaged corneal tissue with healthy donor tissue.

Keratoconus is a progressive eye disorder that affects the shape of the cornea, causing it to thin and bulge into a cone-like shape. While glasses and contact lenses can help manage the symptoms in the early stages, some patients may eventually require surgery to improve their vision and halt the progression of the disease.

Understanding Keratoconus

Before delving into surgical options, it’s essential to understand what Keratoconus is and how it affects vision. Keratoconus typically begins during the teenage years or early adulthood and can lead to blurry vision, increased sensitivity to light, and distorted vision. As the disease progresses, it can significantly impact daily activities and quality of life.

Indications for Keratoconus Surgery

Keratoconus surgery is typically recommended for patients who experience significant vision loss or are unable to achieve adequate vision correction with glasses or contact lenses. Additionally, surgery may be considered to prevent further deterioration of the cornea in advanced cases of the disease.

Types of Keratoconus Surgery

There are several surgical options available for treating Keratoconus, each tailored to the individual patient’s needs and the severity of their condition. Some of the most common surgical procedures include:

1. Corneal Cross-Linking (CXL): This minimally invasive procedure involves applying riboflavin (vitamin B2) eye drops to the cornea, followed by exposure to ultraviolet light. CXL helps strengthen the cornea and halt the progression of Keratoconus.
2. Intacs Inserts: Intacs are small, crescent-shaped implants that are placed within the cornea to flatten and reshape its curvature. This can help improve vision and reduce the irregular astigmatism associated with Keratoconus.
3. Corneal Transplant (Penetrating Keratoplasty or DALK): In severe cases of Keratoconus where the cornea is significantly scarred or thinned, a corneal transplant may be necessary. During this procedure, the damaged cornea is replaced with healthy donor tissue to restore vision.

The Keratoconus Surgical Process

Prior to undergoing Keratoconus surgery, patients will undergo a comprehensive eye evaluation to assess their eligibility and determine the most appropriate treatment approach. The surgical process itself varies depending on the procedure but is typically performed on an outpatient basis under local or general anesthesia.

Recovery and Follow-Up Care

Following Keratoconus surgery, patients will need to follow specific post-operative instructions provided by their surgeon to ensure proper healing and optimal visual outcomes. Recovery times vary depending on the type of surgery performed, but patients can generally expect to experience some discomfort and temporary changes in vision during the initial healing period.

The cornea is a transparent, dome-shaped structure that covers the front of the eye and plays a crucial role in focusing light onto the retina, enabling clear vision. However, like any other part of the body, the cornea can be affected by various diseases and conditions that can impact its function and clarity.

Understanding Corneal Diseases

Corneal diseases can range from mild conditions, such as dry eye syndrome, to more severe conditions, such as keratoconus or corneal ulcers. Some common corneal diseases include:

• Keratoconus: A progressive condition characterized by the thinning and bulging of the cornea, leading to visual distortion and decreased vision.

• Fuchs’ Dystrophy: A condition in which the corneal endothelial cells gradually degenerate, leading to corneal swelling and impaired vision.

• Corneal Ulcers: Open sores on the cornea, often caused by infection or injury, which can lead to pain, redness, and vision loss.

• Corneal Abrasions: Scratches or cuts on the cornea, often caused by trauma or foreign objects, which can lead to pain, redness, and discomfort.

Treatment Options for Corneal Diseases

The treatment options for corneal diseases vary depending on the specific condition and its severity. Some common treatment options include:

• Medications: Topical or oral medications, such as antibiotics or anti-inflammatory drugs, may be prescribed to manage corneal infections or inflammation.

• Eye Drops: Lubricating eye drops or artificial tears may be used to relieve symptoms of dry eye syndrome or to help promote healing in cases of corneal abrasions.

• Contact Lenses: Specialty contact lenses, such as scleral lenses, may be used to improve vision and comfort in patients with corneal irregularities, such as those seen in keratoconus.

• Surgical Procedures: In some cases, surgical procedures may be necessary to treat corneal diseases. These may include corneal transplant surgery (keratoplasty), in which the diseased cornea is replaced with a healthy donor cornea, or procedures to reshape the cornea, such as photorefractive keratectomy (PRK) or laser-assisted in situ keratomileusis (LASIK).

Corneal Disease Specialists at SightMD

The question of whether corneal diseases can be cured depends on the specific condition and its underlying cause. In some cases, such as corneal abrasions or infections, the condition may be temporary and can be effectively treated and resolved with appropriate medications and care. However, for chronic or progressive corneal diseases, such as keratoconus or Fuchs’ dystrophy, a cure may not be achievable. In these cases, the goal of treatment is often to manage symptoms, slow disease progression, and preserve vision for as long as possible. This may involve a combination of medications, contact lenses, and surgical interventions.

While a cure may not always be possible for corneal diseases, there are effective treatment options available to manage symptoms, improve vision, and preserve eye health. If you are experiencing symptoms of a corneal disease, such as redness, pain, or vision changes, it is essential to seek prompt evaluation and treatment from an eye care professional. Early diagnosis and intervention can help prevent complications and improve outcomes.

Keratoconus is a progressive condition characterized by a thinning of the cornea that causes it to lose its symmetrical dome shape. Lopsidedness of the cornea can lead to blurry or distorted vision.

What is keratoconus?

Keratoconus is an eye disorder characterized by the transformation of the cornea from a symmetrical dome to an asymmetric or lopsided cone. The primary function of your cornea is to refract light into your pupil. When light passes through your asymmetrical cornea, it can lead to distortion and blurriness in your vision. Symptoms may start in one eye, but in most cases affects both eyes.

What are the symptoms of keratoconus?

The main sign of keratoconus is a thinning of your cornea that disrupts its natural dome shape. In the early stages of keratoconus, it鈥檚 common to not have any symptoms. As the condition progresses, asymmetry of your cornea can lead to blurred vision and mild to significant distortion of your vision.

Some of the early signs of keratoconus include:

• Rizzuti sign. A steeply curved reflection seen by shining a light on the side of your cornea closest to your temple.
• Fleischer ring. A brown ring of iron deposit around your cornea that鈥檚 most visible with a cobalt blue filter.
• Vogt鈥檚 striae. Vertical lines observed on your cornea that usually disappear when a firm pressure is applied over your eye.

You may also experience:

• corneal swelling
• light sensitivity
• halos in your vision
• eye strain
• irritation
• a persistent desire to rub your eyes
• poor night vision
• nearsightedness (difficulty seeing far away)
• irregular astigmatism (irregular curvature of the eye)

What causes keratoconus?

Researchers still don鈥檛 fully understand why some people develop keratoconus. In most cases, it develops for no apparent reason. It鈥檚 generally thought that both environmental and genetic factors play a role in its development.

• Family history. It鈥檚 thought that some people with keratoconus may carry genes that make them predisposed to its development if they鈥檙e exposed to certain environmental factors.
• Underlying disorders. Keratoconus sometimes occurs in the presence of certain underlying disorders, but a direct cause and effect hasn鈥檛 been established. These disorders include Down syndrome, sleep apnea, asthma, some connective tissue disorders including Marfan syndrome and brittle cornea syndrome, and Leber congenital amaurosis.
• Environmental risk factors. Some environmental risk factors may contribute to the development of keratoconus including excessive eye rubbing and wearing contacts.

How is keratoconus diagnosed?

To make a keratoconus diagnosis, your eye doctor with give you a thorough eye exam and examine your medical and family history.

During the eye exam, your eye doctor may examine:

• the overall appearance of your eyes
• your visual acuity
• your visual field
• your eye movements

You may also undergo a slit lamp exam where your doctor examines your eye with a special light under high magnification. Diagnosis of keratoconus may also involve a specific imaging test called corneal topography to allow your doctor to examine changes to your eye that aren鈥檛 otherwise visible. Corneal topography creates a three-dimensional image of the surface of your cornea.

What is the treatment for keratoconus?

Treatment of keratoconus focuses on maintaining your visual acuity and stopping changes to the shape of your cornea. Treatment options vary based on the severity of the condition and how fast it鈥檚 progressing.

Prescription contacts or glasses

Prescription glasses or soft contact lenses can be used to improve visual acuity in mild cases of keratoconus. Due to progressive changes to your cornea, you may require frequent prescription changes.

Surgery

Some people with keratoconus don鈥檛 tolerate contact lenses well due to discomfort, severe corneal thinning, or scarring. If your vision can鈥檛 be corrected with lenses, you may require corneal transplant or keratoplasty. This surgery involves replacing your corneal tissue with tissue from a donor. It鈥檚 usually only used in severe cases.

Corneal cross-linking device (CXL)

Corneal cross-linking聽(CXL) is a treatment for patients with keratoconus or post-LASIK ectasia (bulging of the cornea after聽LASIK surgery). It is successful in over 90% of cases and can prevent their condition from getting worse. Although approved and used in Europe since 2003, it was not FDA approved in the US until April 2016.

What are the risk factors for developing keratoconus?

Risk factors for developing keratoconus include:

• Family history. About 10 to 20 percent of people with keratoconus have a family history.
• Childhood eye-rubbing. Excessive childhood eye rubbing is thought to increase your risk by 25 times.
• Close genetics relation between parents. Having a close genetic relationship between parents is thought to increase your risk of developing keratoconus by about 3 times.
• Race. Studies suggest that keratoconus rates are higher in people who are Asian compared to people who are Caucasian.
• Atopy. It鈥檚 been suggested that atopy may be associated with the development of keratoconus, possibly due to increased eye rubbing due to eye irritation. Atopy is the genetic tendency to develop allergic diseases such as eczema, asthma, or allergic rhinitis.
