Cataract Surgery & Lens Implantation
Cataract diagnosis, assessment of visual impact, surgical planning and intraocular lens selection based on the eye and patient needs.
What is a cataract?
A cataract is clouding of the natural lens that may cause blurred vision, glare and reduced visual quality. Surgery is considered according to its impact on daily life and examination findings.
Assessment and planning
Evaluation includes refraction, intraocular pressure, lens and retinal examination, with additional measurements when required for intraocular lens calculation.
Lens selection
Lens choice depends on eye health, lifestyle, measurements and realistic visual goals. Options and limitations should be discussed before surgery.
Follow-up
Post-operative drops and follow-up are important. Severe pain, increasing redness or sudden visual deterioration require urgent review.
Why a precise examination matters
Similar visual symptoms can have different causes. Blurred vision may relate to refraction, dry eye, cataract, corneal disease or retinal change. Treatment decisions therefore should not be based on symptoms alone. Examination and appropriate measurements help determine whether the problem requires observation, medication, a procedure or surgery.
Before making a treatment decision
Patients should understand the goal of treatment, alternatives, important limitations, expected recovery and follow-up. Medical conditions, medications and previous eye procedures may affect the choice and timing of treatment. There is no single outcome that applies to every patient.
Follow-up
Follow-up helps assess stability and response to treatment. Severe pain, sudden visual deterioration, increasing redness or new concerning symptoms require prompt medical review. Patients should use prescribed medication as directed and avoid self-medicating the eye.
Preparing for your visit
Bring current glasses, previous reports or scans when available, a medication list and a short history of when symptoms began. These details help guide the assessment and any required testing.
