Cataract Surgery

Cataract surgery is among the most successful and life-changing procedures in modern medicine. When executed with mastery, it is also one of the most precise.
Mr. Mrinal Rana provides a consultant-led surgical service defined by meticulous pre-operative assessment, bespoke lens selection, and a profound respect for your unique lifestyle and visual aspirations.

Understanding Cataracts

A cataract occurs when the eye’s natural crystalline lens becomes progressively opaque. This typically results from proteins within the lens breaking down and clustering, which obstructs the seamless passage of light. While cataracts often develop in both eyes, they may progress at different rates, gradually diminishing your quality of vision.

Aetiology: What Causes Cataracts?

While predominantly associated with the natural ageing process, several factors can accelerate cataract development:

• Environmental & Lifestyle: Prolonged UV exposure, smoking, and excessive alcohol consumption.
• Medical Factors: Diabetes, long-term corticosteroid use, and genetic predisposition.
• Physical Trauma: Previous ocular injuries or prior intraocular surgeries.
• Chronic inflammation: chronic inflammatory conditions requiring use of steroids cause the natural lens to cloud up faster.

Recognizing the Symptoms

Cataracts manifest through a diverse range of visual disturbances, including:

• Blurred, hazy, or "muted" vision.
  
• A yellowed or faded perception of colours.
• Heightened sensitivity to glare and "starbursts," particularly while driving at night.
• The appearance of halos around light sources.
• Frequent, unsettled changes in your spectacle prescription.

The Surgical Pathway: A Definitive Solution

There is currently no pharmacological treatment to reverse a cataract. When visual impairment begins to interfere with your daily life, surgery is the definitive and most effective intervention.

The procedure involves the delicate removal of the clouded lens, which is then replaced by a high-precision Intraocular Lens (IOL). Performed typically as a day-case under local or topical anesthesia, the surgery utilizes micro-incisions and advanced ultrasound technology (phacoemulsification) to ensure a rapid and stable recovery.

Bespoke Lens Selection

The choice of an Intraocular Lens is a pivotal decision. Mr. Rana specializes in matching lens technology to your specific ocular anatomy and visual goals:

• Monofocal Lenses: Engineered for exceptional clarity at a single primary distance (usually far-distance).
• Multifocal Lenses: Designed to provide a broader range of vision across near, intermediate, and far distances, potentially reducing dependency on glasses.The premium lenses range from the subtle variant Monofocal Plus lens to Extended Depth of Focus lens and the Full Range of Vision lens which cater to fixing one focus of vision to all the three focusses of vision.
• Toric Lenses: Specifically crafted to correct pre-existing astigmatism.
• Pin Hole Lens: Designed to reduce the aperture of the eye as the pupil might not be working properly or the cornea is so irregular that it scatters the light causing reduced clarity of vision.

Clinical Safety & Risk Management

Cataract surgery maintains an exemplary success rate of approximately 95–98%. While complications such as infection, inflammation, or retinal detachment are uncommon, Mr. Rana’s expertise in complex surgery ensures that risks are managed with the highest level of clinical vigilance. Comprehensive follow-up care is integral to our practice to ensure optimal healing.

Post-Surgical Adaptation

Following surgery, some patients may experience "dysphotopsias"—temporary visual phenomena like halos or glare. In the vast majority of cases, the brain naturally adapts to these changes (neuroadaptation). Mr. Rana provides ongoing support and assessment during this transition to ensure your visual comfort.

A Considered Approach to Your Vision

As a Consultant Ophthalmic Surgeon specialising in complex and refractive cataract surgery, Mr. Mrinal Rana avoids "one-size-fits-all" solutions. His philosophy centres on clinical transparency, honest dialogue regarding surgical limitations, and a commitment to operating only when it serves the patient's best interests.

Arrange Your Consultation

A consultation is an invitation to clarity, not a commitment to surgery. It is an opportunity to explore your eye health in a calm, professional environment where every question is answered and every decision is made with confidence.
