Your pre-operative assessment

At your pre-operative assessment, our clinical team will examine your eyes and take measurements to ensure that cataract surgery is appropriate for you. We will arrange dates for surgery and your follow-up visits. The measurement of your eye (known as biometry) allows the strength of your new implanted lens to be calculated. Drops to dilate the pupils will be put in both eyes before the doctor’s examination. These drops will blur your vision for up to four hours, and sometimes longer. You will have the opportunity to raise any queries or concerns with members of the SpaMedica team. It is important to bring the following with you:

Important points  
Our eye drops usually cause blurred vision for about four hours. Therefore, you’ll need someone to drive you home after each appointment. You may take a holiday in between appointments, but not for at least one week after the operation. Although complications of cataract surgery are rare, they could cause cancellation of your holiday. It is advisable to go to areas where high quality medical services are available and to notify your travel insurance company about your forthcoming surgery.

Contact lenses
Please remove soft contact lenses (both eyes) 48 hours before your pre-assessment appointment. If you wear permeable or hard contact lenses, these should be removed 7 days prior to your appointment. You can wear them again two hours after the appointment is finished but your vision may still be blurred for a number of hours. Remove your lenses 24 hours before your cataract surgery.

Changes to your eyesight
The cataract operation involves placing a new lens in your eye (lens implant). We have about 60 different strengths of lens implants and we match one to your eye to optimise your visual outcome. We use the latest technology to measure the length and shape of your eye to enable us to determine the ideal power of lens for your specific needs. It is routine to plan the power of your eye, to leave you with minimal requirement for glasses to see clearly in the distance. On rare occasion, we may discuss leaving you short-sighted or long-sighted if we feel this may be of benefit to you. The following are possible refractive (power) outcomes following your surgery that you may wish to discuss:

Myopia (short-sighted)
You will be able to read close up but will require glasses or contact lenses to sharpen your distance vision.

Emmetropia (normal sighted)
You will be able to see at a distance but will need glasses for near vision.

Hypermetropia (medical decision only):
Glasses will be required for distance and near vision.

Astigmatism
In any of the above, if there is significant astigmatism, glasses will be needed at all distances to see clearly. Toric lenses (implants) capable of correcting astigmatism are also available, but unfortunately cannot be offered via the NHS. Please contact SpaMedica for more information. If you have private health insurance and wish to discuss this option, please contact SpaMedica.

Monovision
One eye is focused for near, the other for distance. This can be visually confusing, and we can only create a monovision outcome if your optometrist confirms in writing that you are used to monovision, and that it is in your best interest.

Bifocal and accommodative lenses
These lenses (implants) allow you to see clearly in the distance and for near without the need for glasses. Unfortunately these are not available via the NHS. Please contact SpaMedica for more information or visit our website for details. If you have private health insurance and wish to discuss this option please contact spaMedica.
