Which implant lens should you have?

As with spectacles, there are different implant lenses available. You may be given a choice of using a regular monofocal lens (single-vision power) or a multifocal lens which is designed to give you a degree of spectacle independence for most everyday tasks.

We will discuss with you the type of implant lens that will best suit your needs and the visual outcome you can expect. It is important to note that the advanced multifocal lenses are not suitable for everyone and some patients may still require a spectacle prescription following surgery.


For all patients undergoing cataract surgery, biometry measurements will be taken to ensure that an implant lens of the correct power is selected. This involves sitting at a machine that, without touching the eye, takes various measurements. We can then calculate the most appropriate lens power.

Most patients can be assessed on the day of surgery, but occasionally a pre-assessment is required. This will be discussed at your initial consultation.

If you use contact lenses you must refrain from wearing them for two weeks before biometry is carried out, and for forty-eight hours prior to your surgery.

What do you need to consider prior to surgery?

It is important that we have knowledge of any prescribed medications you are taking. You will probably be asked to continue these in the usual way, but some medications can cause complications during any surgical procedure.

As most cataract surgery is carried out using just drops to numb the eye (referred to as “topical anaesthesia”) there are usually no restrictions on what you may eat and drink prior to admission. Written information will give additional advice should, for example, sedation be required.

Once a decision has been made to proceed with surgery, our secretarial team will liaise with you to arrange a convenient date on one of our operating lists. This will be at one of the ophthalmic units in the Southampton or Guildford areas.

You will receive confirmation of your admission date and time from the hospital bookings department, together with a health questionnaire and some general information about your chosen hospital. The procedure is usually carried out as a day case, with a hospital stay of several hours.

Remember, you should not drive yourself to the hospital. You may want a relative or friend to accompany you, or to drop you off and return to collect you when you are ready to go home. Alternatively if you find getting to and from the hospital difficult, we may be able to offer assistance. Please alert the secretarial team if this is the case as the hospital bookings office is not able to help with transport arrangements.
