Procedure Overview

  • Cataracts are a common eye condition characterised by the clouding of the natural lens inside the eye” – this is due to protein clumping which blocks light from reaching the retina. 

Causes, Symptoms & Types

Causes / Risk Factors

  • Age is a primary factor; the lens naturally becomes less clear with time. 
  • Other contributors: diabetes, long-term steroid use, smoking, excessive UV exposure, eye injury or previous eye surgery. 

Symptoms / Lifestyle Impact

  • Early symptoms of cataract: blurry or cloudy vision (like looking through frosted glass), difficulty in low-light, glare/halos around lights, faded/yellowed colours. 
  • As cataract progresses: more difficulty with driving (especially night), reading, computer/phone use, recognising faces; increased risk of falls due to reduced contrast/depth perception. 

Types of Cataracts

  • Nuclear sclerotic:central nucleus of lens; causes gradual yellowing/browning of vision; may increase myopia. 
  • Cortical: white opacities in outer lens (cortex) appearing as spoke-like; problems with glare, contrast, night vision. 
  • Posterior subcapsular: back of the lens capsule; faster progression; affects reading vision and causes glare. Common in younger patients, diabetics, steroid-users. 
  • Congenital: present at birth or childhood (rare) – demands early intervention to avoid long-term impairment. 
  • Secondary (Posterior capsular opacification – PCO): after surgery, the capsule may become cloudy; treatable by a laser procedure. 

Diagnostic Work-Up

  • Initial baseline assessment: visual acuity, distance & near vision measurement. 
  • Slit-lamp microscopy to examine lens, cornea and retina, determine type and location of cataract. 
  • Pupil dilation drops to allow examination of back of eye (lens capsule, retina) and to screen for co-morbidities. 
  • Ocular biometry / measurements: pre-surgery lens power calculation (IOL power), corneal measurements, axial length.
  • Mr Sira uses advanced technology for the most accurate results and a personalised visual outcome. 
  • Patients’ lifestyle needs (driving, screen work, hobbies) guide lens-choice and timing of surgery. 

Surgical Treatment & Lens Options

When to proceed with surgery

  • The only definitive treatment is removal of the cloudy natural lens and replacement with an artificial intraocular lens (IOL). 
  • Surgery is recommended when cataracts begin to significantly interfere with daily life (driving, reading, screen use) rather than waiting for “the worst”. 

Procedure details

  • Typical duration: ~10-15 minutes per eye. 
  • Performed under local anaesthesia (numbing eye-drops and/or injection); patient is awake but comfortable. 
  • Approach: small incision in cornea → ultrasonic fragmentation (phacoemulsification) of the cloudy lens → removal → insertion of the customised IOL. 

Lens (IOL) choices

  • Monofocal: one fixed distance (typically distance); reading glasses likely needed.  
  • Toric: for patients with astigmatism – corrects irregular corneal shape plus cataract. 
  • Extended Depth of Focus (EDOF): offers a broader range of vision with fewer visual side-effects (halos/glare) than classic multifocal. 

Aftercare, Recovery & Outcomes

Immediate recovery

  • Day-case procedure – patient goes home same day. 
  • Some mild sensations: grittiness, watering, mild discomfort in treated eye for a day or two. 
  • Many patients notice clearer vision within 24-48 hours; full stabilisation may take a few weeks. 

Aftercare plan

  • Eye-drops: usually antibiotic + anti-inflammatory drops to prevent infection and control inflammation. 
  • Follow-up consultation: the clinic mentions a review ~2 weeks after surgery to check healing and answer questions. 
  • Activity advice: Avoid strenuous exercise, heavy lifting, swimming, and rubbing the eye for a short period. Use protective eyewear or shield. 

Outcomes & long-term outlook

  • Most patients enjoy a significant improvement in vision and quality of life. Colours often appear brighter; night vision and glare reduction typically improve once the cloudy lens is removed. 
  • The longevity of results is very good; nonetheless age-related changes in vision still may occur, so regular eye checks remain important. 

Risks

  • Important risks (though rare) include: infection, inflammation, visual disturbances (e.g., halos/glare), posterior capsule rupture, need for further surgery. These are discussed during consultation. 

Finance & Practical Considerations

  • Private cost starts at around £2,500 per eye though this depends on lens type and any additional treatments. 
  • Private treatment advantages: short waiting times, advanced lens choices tailored to lifestyle, continuity of care with the same consultant
