A cataract is a gradual clouding of the eye’s natural lens, which sits just behind the pupil. Over time your vision looks blurry, hazy, or less colourful—much like looking through a fogged-up window. As a cataract progresses, you might find it harder to read or drive at night due to increased glare from headlights.
Arthur Okonkwo is an expert in cataract surgery, replacing the cloudy lens with a clear artificial one, which restores vision. There are lots of different lens choices and which we can tailor to your needs please contact us today to discuss.

Keratoconus is a condition where the cornea—the clear, round front surface of your eye—thins and begins to become an irregular shape preventing light from focusing correctly on the retina, leading to distorted vision and increased sensitivity to light and glare.

There are two pillars to keratoconus management. Firstly, visual preservation through crosslinking. Secondly visual rehabilitation with glasses, contact lenses; and in later stages CAIRS or corneal transplantation.

Arthur Okonkwo has published the fantastic results of Keratoconus treatment in Leeds.  He runs an NHS clinic receiving Keratoconus referrals and treating patients across Yorkshire and the North East.

This condition affects the innermost layer of the cornea, called the endothelium. These cells act like tiny pumps, constantly removing fluid to keep the cornea clear. In Fuchs’ Dystrophy, these cells slowly die off, causing fluid to build up and the cornea to swell.

The hallmark symptom is often “morning blurriness.” that may clear during the day. The treatment for this condition is a very thin corneal transplant (DMEK) to give you healthy endothelial cells and restore vision.

Corneal swelling (oedema) causes the cornea to lose its transparency, which can cause vision to become cloudy or blurred. You may also see “halos” or rainbows around lights and your eye may be painful.

Oedema is most commonly caused by Fuchs Endothelial Dystrophy but may also be caused by eye infections, or complications after eye surgery. Treatment focuses on reducing the swelling to improve the vision and comfort. This can be done via corneal transplantation (DMEK or DSAEK) or laser eye surgery (PTK).

The cornea must be perfectly clear to allow light to pass through. Corneal scarring occurs when the tissue is damaged by an injury, an infection (like shingles or herpes), or certain diseases. This opaque scar tissue blocks or scatters light, leading to blurred vision or even vision loss depending on the scar’s size and location.

If a scar is small and off to the side, it may not affect your vision much at all. However, if the scar is central, you may require specialized contact lenses to smooth out the surface or, in more advanced cases, laser eye surgery (PTK) or corneal transplantation (PKP/DALK) to clear the cornea and improve the vision.

RCES occurs when the outermost layer of the cornea (the epithelium) does not stick properly to the layer beneath it. This causes the surface layer to peel off easily, much like a blister. It often happens spontaneously, frequently upon waking up when the eyelid pulls on the cornea as you open your eyes.

The condition is notoriously painful and can cause redness, watering, and light sensitivity, more so in the mornings. Management usually involves heavy lubrication with ointments at night to prevent the eyelid from sticking or laser eye surgery (PTK) to help the surface layer “anchor” more securely to the eye.

A pterygium (often called “Surfer’s Eye”) is a non-cancerous, fleshy growth that starts on the white of the eye and can spread onto the cornea. It is often shaped like a wedge and is linked to long-term exposure to UV light, wind, and dust (more common in Australia, Africa and Asia).

While a pterygium is usually harmless, it can become red and irritated. If it grows large enough it can blur your vision. In these cases, it can be surgically removed. Surgical removal should also be considered prior to cataract surgery to improve visual outcomes.

Arthur Okonkwo’s fellowship training at The Royal Victorian Eye and Ear Hospital in Melbourne gave premier training in Pterygium surgery. Arthur Okonkwo runs an NHS clinic treating patients with Pterygium from Leeds and Yorkshire.

Dry eye occurs when your eyes either don’t produce enough tears or produce poor-quality tears that evaporate too quickly. This can cause intermittent blurred vision, stinging, burning, a “gritty” sensation, or even paradoxical watery eyes.

Treatment usually involves artificial tears, warm compresses, or lifestyle changes like taking breaks from digital screens.

Arthur Okonkwo has an interest in dry eye after undertaking further training at Clinic Barcelona Institute of Ophthalmology Dry Eye Centre. He has also developed Comfort – Dry Eye App to help educate patients about their dry eye.

Myopia is a common condition where you can see objects clearly when they are close to you, but distant objects appear blurred.

Myopia typically develops during childhood and stabilizes in early adulthood. It can be corrected with glasses or contact lenses. If an individual is suitable laser eye surgery or an implantable contact lens can reduce dependence on glasses or contact lenses.

Arthur Okonkwo has published on treatment options for myopia.  He runs an NHS clinic receiving myopia referrals (post corneal transplantation and post cataract surgery) and treating patients with the condition from Leeds, Yorkshire, the North East and the East Midlands.

Hypermetropia is a common condition where distant objects are often clearer than those up close. Young people can often use their eye muscles to compensate, but this can lead to eyestrain and headaches.

As we age, the ability to “force” the eye into focus diminishes, making the blurriness more noticeable. It can be corrected with glasses or contact lenses. If an individual is suitable laser eye surgery, an implantable contact lens or premium lens, they can reduce dependence on glasses or contact lenses.

Presbyopia is a natural, age-related change that happens to everyone, usually starting in our 40s. The lens inside the eye stiffens, making it difficult for the eye to change focus from distance to near objects (like reading a menu or a phone).

It can be corrected with multifocal glasses, reading glasses, monovision or multifocal contact lenses. If an individual is suitable laser eye surgery or a premium lens, they can reduce dependence on glasses or contact lenses.

Arthur Okonkwo holds a Postgraduate Diploma with Distinction in Cataract and Refractive Surgery from Ulster University with a focus on presbyopia treatments.

Astigmatism occurs when the cornea or the lens inside the eye is shaped more like an oval (or a rugby ball) rather than a round sphere (like a football). This causes blurred vision at all distances.

It can be corrected with glasses or contact lenses. If an individual is suitable laser eye surgery, an implantable contact lens or a premium lens, they can reduce dependence on glasses or contact lenses.
