Monofocal lenses
Usually selected to provide clear focus at one main distance. Glasses may still be needed for other distances and for astigmatism.
Cataract care
Cataract & lens surgery
A careful cataract assessment should connect the change in your sight with the right time for surgery and an appropriate lens plan.
Understanding the concern
A clear diagnosis comes before a treatment plan
A cataract is a clouding of the eye's natural lens. It often develops gradually and can make reading, driving at night, recognising faces or managing glare more difficult.
Surgery is considered when the cataract meaningfully affects daily life or makes another eye condition harder to assess or treat. The decision is individual: the examination, health of the retina and optic nerve, visual priorities and lens measurements all matter.
What patients notice
Reasons to arrange a cataract assessment
These features can overlap with other eye conditions. Examination is needed to establish the cause.
- Cloudy, blurred or dim vision
- Increasing glare or halos around lights
- Difficulty driving at night
- Colours appearing faded or less distinct
- Frequent changes in glasses without lasting improvement
- Reduced ability to read or perform detailed work
Specialist assessment
What the consultation may involve
The purpose of assessment is not only to confirm a cataract. It is to understand the whole eye and set realistic expectations for vision after surgery.
01
Vision and eye health
Visual acuity, eye pressure, slit-lamp examination and a dilated retinal examination help identify cataract and other factors affecting sight.
02
Lens measurements
Biometry and corneal measurements are used to calculate intraocular lens power and discuss the intended focus after surgery.
03
Retina and optic nerve
OCT or other imaging may be advised when macular, diabetic, glaucoma or retinal concerns could influence the result or lens choice.
Treatment planning
Planning surgery and the replacement lens
Cataract surgery removes the cloudy natural lens and replaces it with an intraocular lens. The specific plan depends on eye measurements, ocular health, lifestyle and informed discussion.
Toric lenses
Designed to reduce selected levels of corneal astigmatism. Suitability depends on stable measurements and the health of the eye.
Extended-range or multifocal lenses
May reduce dependence on glasses for more than one distance in carefully selected eyes, but optical trade-offs and individual expectations require detailed discussion.
Complex cataract care
Previous trauma, weak lens support, dense cataract, prior surgery or retinal disease may require additional planning or combined expertise.
From first assessment to follow-up
- 01Comprehensive consultation and dilated eye examination
- 02Biometry, corneal measurements and any indicated retinal imaging
- 03Discussion of visual priorities, risks, alternatives and lens options
- 04Surgery plan with personalised preoperative instructions
- 05Postoperative drops, protection and scheduled follow-up

Individualised planning for cataract and lens surgery
Prof. Amer Awan's cataract work includes routine and complex surgery, lens planning and care when retinal disease or previous retinal surgery affects the decision. The recommended approach is based on examination, measurements and the patient's visual priorities.

Questions patients ask
About Cataract surgery
Does every cataract need surgery?
No. Early cataract can often be monitored if daily activities remain comfortable. Surgery is usually discussed when the cataract is limiting useful vision or interfering with management of another eye condition.
Will I be completely free from glasses?
That cannot be guaranteed. The likely need for distance, intermediate or reading glasses depends on the lens selected, astigmatism, healing and the health of the rest of the eye.
Can cataract and retinal problems be assessed together?
Yes. A dilated retinal examination and, when indicated, OCT imaging can help identify macular or retinal factors that should be considered before surgery.
What should I expect after surgery?
Most patients receive eye drops and activity guidance and return for follow-up. Recovery and restrictions vary, so the instructions from your own surgical team take priority over general website information.
