What is an Astigmatism?

Astigmatism is a common refractive error resulting from an irregular shape in the cornea or lens, causing blurred or distorted vision. Unlike spherical corneas, those with astigmatism often have a more football-shaped cornea, leading to uneven light focus on the retina and distorted images. Corrective measures range from eyeglasses and contact lenses to surgical procedures like LASIK, aimed at reshaping the cornea for improved visual clarity.

About Astigmatism

Symptoms Causes Complications

Signs and Symptoms of Astigmatism

Are you experiencing blurred vision, especially during both near and far tasks? Do you find yourself grappling with eyestrain and headaches, particularly after extended periods of focused visual activities like driving at night or prolonged computer use? These could be indicative of astigmatism, a common refractive error affecting the cornea or lens. Understanding the signs and symptoms is crucial for maintaining optimal eye health.

Astigmatism often presents itself as varying degrees of blurred vision, impacting both distance and near vision. If you’ve noticed a persistent blurriness that doesn’t seem to improve, it might be time to consider the possibility of astigmatism. Additionally, astigmatism can lead to eyestrain and headaches, especially during concentrated periods of visual tasks. For individuals who spend extensive hours in front of a computer screen, these symptoms may manifest as asthenopia, or eyestrain, rather than clear visual difficulty. This makes regular eye check-ups essential, especially if you engage in prolonged computer work, as undiagnosed astigmatism could contribute to overall discomfort.

The importance of recognising astigmatism symptoms becomes even more evident when considering the impact on daily activities. Tasks such as driving at night or working on a computer for extended periods can become challenging and uncomfortable without proper vision correction. Addressing these symptoms promptly is crucial not only for visual clarity but also for overall eye health and comfort.

At our state-of-the-art facility, Precision Vision in the heart of London, we specialise in identifying and treating astigmatism. Led by the esteemed surgeon Dr. CT Pillai, our focus on personalised care ensures that you receive the attention and expertise needed to alleviate the effects of astigmatism. Regular eye check-ups and early detection are key elements of our approach, emphasising proactive measures to enhance your eye health. Don’t let astigmatism compromise your visual comfort – consult with us to experience precision in eye care tailored to your needs.

Understanding Causes and Solutions 

Astigmatism, a common refractive error affecting approximately 9 out of 10 individuals, it arises from the misshapen cornea, resembling the curvature of a rugby ball rather than a spherical shape. Unlike an evenly rounded cornea, the distorted curvature leads to incorrect bending of light, resulting in a blurred image and a phenomenon known as ‘ghosting.’ 

This distortion becomes particularly noticeable when viewing letters on a screen, where the patient perceives a ghost image alongside the original writing. For instance, when reading subtitles on the TV or glancing at digital train timetables/signs at the airport, the effects of astigmatism become apparent.

It is crucial to clarify that astigmatism is not classified as an eye disease but rather a refractive error, akin to short-sightedness and long-sightedness, all of which involve focusing issues. The key culprit in astigmatism is the irregular shape of the cornea, disrupting the proper bending of light and causing visual distortions. The most common symptom is blurred vision, and ‘ghosting’ further adds to the challenge, making tasks like reading or viewing digital displays more cumbersome.

Despite its prevalence, astigmatism often goes unnoticed, especially in mild amounts. Many individuals may not realise they have astigmatism until they encounter difficulties with tasks requiring clear vision. This highlights the importance of regular eye check-ups, as early detection allows for timely intervention and personalised treatment options.

At Precision Vision in the heart of London, our dedicated team, led by renowned surgeon Dr. CT Pillai, specialises in identifying and addressing the root causes of astigmatism. Our approach goes beyond symptom management, focusing on personalised care to correct the misshapen cornea and restore clear vision. 

Through cutting-edge treatments and a commitment to patient well-being, we strive to provide solutions that not only alleviate the effects of astigmatism but also enhance overall eye health. Don’t let the subtle nuances of astigmatism compromise your visual clarity – consult with us to experience precision in eye care tailored to your unique needs.

Astigmatism: Understanding Potential Complications 

While astigmatism itself poses minimal complications, its impact on eye health, especially in children, is worth noting. Astigmatism can differ significantly between the two eyes, potentially leading to amblyopia, commonly known as a lazy eye. In children, the condition may prompt the brain to prioritise the dominant eye for focus and visual function, inadvertently causing the weaker eye to become lazy.

Early detection through routine eye tests with an optometrist is crucial to identify and address this potential complication.

Though complications are relatively rare, the risk of amblyopia underscores the importance of proactive eye care. Regular eye examinations, particularly in childhood, serve as a preventive measure to detect and manage astigmatism-related issues promptly.

At Precision Vision in the heart of London, our expert team, led by Dr. CT Pillai, emphasises the significance of early intervention. Through comprehensive eye tests and personalised care, we aim to mitigate potential complications, ensuring optimal eye health for all ages.

Refractive Solutions

Glasses & Contact Lenses Refractive Surgery

The most prevalent and cost-effective method for correcting long-sightedness is through the use of glasses, which effectively redirect light onto the retina. Depending on the extent of your astigmatism, you may find it necessary to wear glasses consistently or only for specific visual activities like night driving, watching TV, or using a computer.

While contact lenses can be an alternative, their application is somewhat limited, particularly with higher levels of astigmatism. The potential rotation of the contact lens in the eye during blinking can result in suboptimal correction, dissatisfying many users. 

This limitation becomes particularly apparent when engaging in visual tasks that demand precise distance correction, such as activities like shooting, golf, or archery. For these reasons, glasses remain a preferred and more reliable option for correcting long-sightedness associated with astigmatism.

Refractive surgery becomes a viable option once the prescription stabilises, typically around the early 20s. Laser procedures such as LASIK and LASEK are the most common types, both involving the reshaping of the cornea to enhance light focus on the retina.

Another surgical alternative is Implantable Contact Lenses (EVO Visian ICLs), also known as phakic IOLs. This option is suitable for individuals with prescriptions too high for laser surgery or those with thin corneas. EVO Visian ICLs are surgically placed behind the iris to aid in focusing light onto the retina, and they carry no risk of rejection by the body.

For individuals experiencing presbyopia (the need for reading glasses, typically after the age of 45), Clear Lens Replacement presents a refractive surgery option. In this procedure, the crystalline lens of the eye is replaced with an artificial (intraocular) lens, refocusing light to enable clear vision at both distance and near. Trifocal lenses are commonly implanted, offering a comprehensive solution for age-related vision changes.
