A cataract is a clouding of the eye’s lens. The majority of cataracts are age related. Removing a cataract and replacing it with an artificial lens results in improved vision in approximately 98% of patients. This is thanks to advances in surgical techniques and modern intra-ocular lenses.
In the case of age-related cataracts, patients may begin to notice reduced distance vision, haloes around lights or a general reduction in visual clarity. Although it is common to have some degree of cataract by age 60, they may not require surgery.
Currently the only way to remove a cataract is with surgery. Early cataracts can be safely monitored by Optometrists and Ophthalmologists. Surgery is necessary when vision is reduced to affect quality of life or prevent activities such as driving.
Cataracts are removed by either an operation known as Phaecoemulsification or a combination of laser-assisted (femtosecond) cataract surgery and Phaecoemulsification. Dr Cohn can advise which is appropriate for you.
Both are usually performed in a day surgery under local or topical anaesthetic. If you have other anaesthetic requirements these can be discussed and arranged as appropriate.
Just as each person is different, so too is the requirement for the type of intra-ocular lens needed at the time of surgery. If you decide to proceed with cataract surgery you will be measured using specialised equipment to determine the correct lens power for you. Different lens options include correction for distance vision, toric lenses and multi-focal lenses. These options will be discussed with you.
Patients need to be driven home on the day of surgery. There will be a regime of drops to use in the initial post-operative period. Recovery from the operation is usually quick and while discomfort is normal after any operation most patients find this passes very quickly.
A follow up appointment with Dr Cohn will be made for you. If you require an earlier review she is always available to see you or discuss matters over the telephone.
