Understanding Cataracts: Causes, Symptoms & Treatment Options

A patient-friendly guide explaining what cataracts are, how they form, typical signs, and a walkthrough of the modern surgical options available at your clinic.

Sample:

Cataracts occur when the natural lens of the eye becomes cloudy, gradually impairing vision. While age is the most common factor, other causes include UV exposure, diabetes, trauma, or long-term use of certain medications such as steroids. Symptoms to be aware of Blurred or dim vision Difficulty seeing at night or in low light Glare or halos around lights Frequent changes in eyeglass prescription Treatment approachesWhen cataracts begin to affect daily life, surgery is the only definitive treatment. At London Eye Specialist, we employ phacoemulsification combined with implantation of premium intraocular lenses (e.g. multifocal, toric) to correct astigmatism and reduce dependence on spectacles. What to expect during surgery & recoveryThe procedure is minimally invasive, typically done under local anaesthetic with sedation. Many patients return home the same day. Postoperative care includes eye drops, avoiding strenuous activity, and follow-ups to monitor healing. For those curious about whether you’re a candidate, feel free to schedule a consultation — early evaluation ensures better outcomes.
