Understanding Recurrent Corneal Erosions: Causes, Symptoms, and Treatment Options

Causes of Recurrent Corneal Erosions

Recurrent corneal erosions occur when the outermost layer of the cornea, called the epithelium, fails to adhere properly to the underlying layers. This leads to episodes of pain, tearing, blurred vision, and sensitivity to light. The condition is often referred to as “corneal erosions” or “recurrent corneal erosion syndrome.”

There are several factors that can contribute to the development of recurrent corneal erosions. One common cause is trauma to the eye, such as a scratch, foreign body, or previous eye surgery. Other causes include underlying conditions like dry eye syndrome, corneal dystrophies and certain genetic disorders. People who have experienced a corneal abrasion in the past may also be more prone to recurrent corneal erosions.

Symptoms of Recurrent Corneal Erosions

The symptoms of recurrent corneal erosions can vary from person to person, but commonly include episodes of sharp eye pain, redness, tearing, and sensitivity to light upon waking in the middle of the night or early morning. Some people experience blurred vision or a sensation of having a foreign body in the eye. These symptoms can be debilitating and significantly impact daily activities and quality of life.

Treatment Options for Recurrent Corneal Erosions

The treatment approach for recurrent corneal erosions depends on the underlying cause and severity of the condition. In mild cases, conservative management may be sufficient. This can include the use of lubricating eye drops, ointments, or moisture chamber goggles to promote corneal healing and reduce symptoms. In more severe cases, additional treatment options may be considered.

Medications for Managing Recurrent Corneal Erosions

Medications such as hypertonic saline drops or ointments may be prescribed to help reduce corneal swelling and improve epithelial adhesion. These medications work by drawing out excess fluid from the cornea and promoting healing. In some cases, antibiotic ointments may also be used to prevent infection and promote epithelial healing.

Surgical Interventions for Recurrent Corneal Erosions

In cases where conservative measures and medication fail to provide relief, laser or surgical interventions may be necessary. There are two surgical options which Dr. Erica can offer:

  1. A laser surgical procedure called phototherapeutic keratectomy (PTK) which can be performed onsite with our state of the art Zeiss refractive laser suite.
  2. The alternative is an in-office surgical procedure called a superficial keratectomy with diamond burr application. At the same time, depending on the distribution of the corneal erosions, an anterior stromal puncture may also be offered.

Following both surgical procedures a contact lens (bandage contact lens with no prescription) is placed on the eye and remains there for one month – this is important to initially reduce pain, and secondarily to promote healing and stabilization of the newly regenerated epithelium.

Lifestyle Changes to Prevent Recurrent Corneal Erosions

In addition to medical and surgical interventions, certain lifestyle changes can help prevent recurrent corneal erosions. It is essential to avoid rubbing or touching the eyes excessively, as this can disrupt the epithelial layer and trigger erosions. Protecting the eyes from trauma by wearing appropriate eye protection during sports or other activities is also recommended. Maintaining good eye hygiene, such as regularly cleaning contact lenses or using preservative-free lubricating drops, can also help prevent recurrent corneal erosions.

Recurrent corneal erosions can be a challenging and painful condition, but with proper diagnosis and treatment, individuals can find relief and improve their quality of life. If you are experiencing symptoms of recurrent corneal erosions, book an appointment with our subspecialist corneal surgeon Dr. Erica for a comprehensive evaluation and personalized treatment plan. Take proactive steps to maintain healthy eyesight and minimize the impact of recurrent corneal erosions on your daily life.

Introduction to Phototherapeutic Keratectomy (PTK)

Phototherapeutic Keratectomy (PTK) is a laser-based treatment used to correct a variety of corneal conditions. It is minimally invasive and generally highly effective. A laser is used to precisely remove damaged or irregular corneal tissue, allowing for the restoration of visual acuity and the improvement of overall eye health.

Common reasons for having PTK treatment are: recurrent corneal erosions, corneal scars or opacities. These can occur due to corneal dystrophies, trauma, infections, or previous eye surgeries, and can significantly impact vision.

How does the procedure work?

The procedure of Phototherapeutic Keratectomy is a well-established and highly precise surgical technique. Before the surgery, the patient receives topical anesthesia to the eye to ensure comfort. The surgeon then uses an excimer laser to ablate the damaged or irregular corneal tissue, following a predetermined treatment plan.

The excimer laser emits pulses of ultraviolet light, which are absorbed by the corneal tissue, causing it to evaporate. The laser is programmed to remove a specific amount of tissue based on the patient’s individual needs. This precise ablation allows for the reshaping of the cornea and the removal of any abnormalities.

During the procedure, the surgeon carefully monitors the cornea to ensure accurate tissue removal. The laser is quick, taking seconds to minutes. Exact time depends on the extent of the corneal condition being treated. After the procedure, a protective contact lens is placed on the eye to aid in the healing process and assist with pain relief.

Understanding Phototherapeutic Keratectomy: Benefits, Risks, Preparation and Treatment Options

Benefits and Risks of Phototherapeutic Keratectomy

Phototherapeutic Keratectomy offers several benefits for patients who undergo the procedure. One significant advantage is the ability to address a wide range of corneal conditions, providing relief from discomfort, improved vision, and enhanced quality of life. It is a relatively quick, minimally invasive and straightforward procedure, and most patients experience minimal pain or discomfort during the surgery. There will be some temporary discomfort after the surgery which we will help you manage with oral pain medication and contact lens application.

As with any surgical procedure, there are associated potential risks. These risks include infection, corneal haze, glare, dry eyes, potential refractive change, a temporary increase in light sensitivity and rarely infection. If this procedure is recommended these risks will be discussed and weighed against the benefits of the procedure.

Preparing for a Phototherapeutic Keratectomy

It is important  to arrange for transportation to and from the surgical facility, as your vision will be temporarily impaired immediately after the procedure. Having someone to provide support and assistance during the recovery period is also recommended.

Recovery and Aftercare Following a Phototherapeutic Keratectomy

After the surgery you may experience mild discomfort, watering of the eyes, and sensitivity to light. You will be prescribed eye drops and medications to alleviate these symptoms and promote healing. It is important to avoid rubbing or touching the eyes, wear protective eyewear and refrain  from strenuous activities or swimming in the early period after the procedure.

During the recovery period, you will have follow-up appointments to monitor the healing process and assess visual acuity. It is crucial to attend these appointments and communicate any concerns or changes in vision.
