Symptoms and Treatment of Keratoconus

keratoconus is a corneal condition that occurs when your eyeballs are unevenly shaped. There are several treatment options available, including implantable ring segments and LASIK surgery. The main symptom of keratoconus is the inability to wear contacts and glasses.

Symptoms of Keratoconus can vary in severity depending on the stage of the disease. Some patients experience blurry vision, double vision, sensitivity to bright light, and occasional eye irritation. Some may also experience difficulty with depth perception and night vision.

Keratoconus may be caused by genetic predisposition or environmental factors, such as overexposure to ultraviolet rays, contact lenses, or eye trauma. The disease can affect both males and females equally. However, African-Americans and Latinos have a higher risk of developing the disease than other groups.

Keratoconus symptoms may appear in the early teenage years or later in life. The symptoms may include double vision, blurred vision, sensitivity to bright light, a halo effect around lights, and frequent changes in vision.

The shape of the cornea (the eye’s outermost lens) affects the quality of vision. The cornea is normally dome-shaped. When it bulges outward, it forms a cone shape and distorts the light entering the eye. This changes the way light enters the eye and causes blurred vision.

Some patients develop corneal blisters that cause swelling and pain. The blisters can also cause fluid to accumulate in specific layers of the cornea. This causes the cornea to swell, causing scarring and reduced vision.

The disease can be treated in various ways depending on the stage of the disease. In the early stages, patients can correct their vision problems with soft contact lenses or glasses. In more advanced stages, patients may require a corneal transplant or rigid gas-permeable contact lenses.


Several factors play a role in the causes of Keratoconus. These include genetics, environmental factors, and allergies. Regardless of the cause, early diagnosis is vital to ensuring proper treatment. The aim of treatment is to improve vision and prevent further vision loss.

Keratoconus is a progressive eye disease that is caused by a loss of structure in the cornea. This cornea is a thin layer of tissue that coats the eye and helps to focus light. The loss of structure in the cornea can cause blurred vision and distorted vision. It can also cause increased sensitivity to light.

Keratoconus is inherited, and a person’s chances of developing the disease are greatly affected by their family history. Researchers are currently investigating the relationship between keratoconus and genetics. The condition can also be caused by a physical condition, eye allergies, and other environmental factors.

Keratoconus symptoms usually begin in the late teens or early 20s. Over time, the condition can cause distorted vision, frequent changes in eyeglass prescription, and increased sensitivity to light. In advanced cases, keratoconus can result in the need for a corneal transplant.

Symptoms vary from person to person. Some people may experience blurred vision, light sensitivity, or a loss of the ability to see in dim light. Other people may not experience any symptoms.

Keratoconus is typically diagnosed through an eye exam. The exam will include measurements of the cornea’s thickness and shape. It may also include ultrasound tachymetry, which can help doctors track the progress of the disease.


Symptoms of keratoconus include blurred vision, eye redness, and swelling. This condition progresses over time and can cause distorted vision and scarring of the cornea. In later stages, surgical treatments may be necessary.

Keratoconus treatments aim to prevent the progression of the condition and improve vision. Some of the treatments include soft contact lenses, corneal collagen cross-linking, and corneal transplantation. However, not all people with keratoconus can tolerate these treatments.

The goal of corneal collagen cross-linking is to strengthen the tissue and bonds of the corneal collagen fibers. This minimally-invasive treatment has been performed successfully around the world for the past decade. The procedure involves applying a special riboflavin solution for 30 minutes to the cornea. The riboflavin is then activated by UV light. The resulting stronger bonds between the collagen fibers prevent the cornea from bulging. This procedure is FDA-approved.

Keratoconus treatments can also include an Intacs ring, which is a plastic C-shaped ring that is inserted into the cornea to strengthen and reshape it. However, the ring does not stop the progression of the disease, and some patients still need glasses for corrective vision.

Corneal transplantation (penetrating keratoplasty) is an advanced treatment option that involves replacing the cornea with healthy donor tissue. This surgery reshapes the cornea and restores vision. It is recommended for individuals with advanced keratoconus, as eyeglasses may not be enough to provide clear vision.

Some people with keratoconus may have a genetic predisposition for the disease. In this case, a family member may carry the gene for the disorder. In addition, environmental risk factors such as repeated eye-rubbing or atopy may contribute to the development of the disease.

LASIK surgery

LASIK surgery is used to correct refractive errors. This can be nearsightedness, astigmatism, or both. A surgeon removes some corneal tissue and reshapes the cornea to allow clear vision without glasses.

The procedure is safe and has a low risk of sight-threatening complications. It also has a high success rate. It is a popular elective procedure. However, not everyone who wants to have LASIK is a good candidate.

Before deciding to undergo LASIK, you need to be sure that your cornea is healthy and that you are not at risk for keratoconus. A topography test will help determine this. During a topography test, your doctor will create a color map of your cornea, and it will be tested to see if it is irregular. You should disclose any family history of keratoconus to your ophthalmologist.

There is a small risk of keratoconus ectasia following LASIK. However, it has been shown that Corneal Collagen Cross-Linking can prevent the condition from worsening. This procedure, which is used since 2016, combines ultraviolet light with vitamin B2 drops to cross-link the cornea’s fibers.

The procedure is designed to prevent keratoconus from progressing and is effective for about 90 percent of patients. It is also used to treat moderate to severe myopia.

Patients may also choose to undergo Cross-Linking treatment in conjunction with PRK, a surface laser eye surgery that corrects refractive errors by reshaping the cornea. During this treatment, the surgeon will surgically implant small ring segments into the cornea to flatten the shape of the cornea.

Implantable ring segments

ICRS (intrastromal corneal ring segment) is a small device that is implanted in the cornea. It is made of synthetic material and has a triangular cross-section. It is used to treat keratoconus. It is an effective and reversible treatment option for keratoconus patients.

The ICRS procedure is an alternative to keratoplasty. The goal of ring implantation is to reduce corneal steepening and improve visual performance. The procedure can be performed in just 30 minutes and does not require the cornea to be flap dried. The ring segments are inserted between the stroma layers of the cornea. The corneal ring is made of inert plastic.

Keratoconus is a corneal degenerative condition that causes poor vision in young people. It usually affects only one eye and worsens over the course of the teenage years.

Intrastromal corneal ring segments were initially used to treat astigmatism in keratoconus. There are several different designs. They include Intacs (US), Ferrara (Brazil), Myoring (Austria), and Intraseg (UK).

Intacs is the most common brand of corneal ring used in the U.S. and has received FDA approval for low to moderate myopia correction. Intacs segments can be implanted through the peripheral corneal channels.

ICRS is an effective, reversible treatment option for keratoconus. They are also effective in patients who are intolerant to hard contact lenses. Several studies have been conducted to assess the long-term outcome of ICRS. Some studies show that the degree of coma-like aberrations is reduced after implantation.

Scleral lenses

Whether a patient is suffering from keratoconus, pellucid marginal degeneration, or another ocular surface disease, scleral lenses provide excellent vision correction. They are also safe and effective. The scleral lens is a large, non-invasive, stable lens that is designed to vault over the cornea.

The post-lens fluid reservoir ensures that the ocular surface is hydrated and prevents the formation of keratinized lid margins. This allows for better visual acuity and prevents the development of cicatricial entropion.

Several studies have evaluated the safety of scleral lenses in a variety of patient populations. However, few studies evaluated keratoconus in isolation. These studies offer foundational points of comparison, but many were unable to account for underlying comorbidities. This study was designed to do just that.

A total of 86 subjects qualified for the study. The study was designed to assess the safety of modern scleral lenses in patients with keratoconus.

The study consisted of three stages. The first stage consisted of a screening of 385 subjects with keratoconus. The subjects were fit with scleral lenses in one or both eyes. The subjects were fit for a minimum of one year and no more than two years.

The second stage consisted of a screening of all study subjects. The subjects were included, regardless of pre-existing morbidity, whether they had prior corneal surgery, or whether they had worn a contact lens modality other than scleral lenses.
