Vision after surgery
Most cataract surgery will leave the patient with optimised distance vision. We measure the clarity or sharpness of vision using distance vision charts. If you have a vision of 6/6 that means you have normal visual acuity at distance. You can see clearly at 6 meters what should normally be seen at that distance. If you have poor distance vision measured as 6/60, it means that you must be as close as 6 meters to see what a person with normal vision can see at 60 meters, so your vision is ten times worse than normal.
Having 6/6 vision does not necessarily mean you have perfect vision. It only indicates the sharpness or clarity of vision at a distance. Other important vision skills, including peripheral awareness or side vision, eye coordination, depth perception, focusing ability and colour vision, contribute to your overall visual ability.
Some people can see well at a distance but are unable to bring nearer objects into focus. This condition can be caused by hyperopia (farsightedness) or presbyopia (loss of focusing ability). If you have had a monofocal lens after cataract surgery and attain 6/6 vision, it is unlikely that you will be able to read close-up without spectacles as the lenses do not change focus and cause complete presbyopia. Edgbaston Eye Consultants offers specialist lenses that give you distance and near vision so that you don’t need to wear spectacles for your day to day vision.
If you see items that are close but cannot see those far away. This condition may be caused by myopia (nearsightedness). Some people use this phenomenon in one eye to see near after surgery, while the other eye has a distance lens, so they don’t require spectacles for day to day vision (monovision). This only suits a minority of patients if it is not carefully checked beforehand, the difference between the eyes can cause a feeling of imbalance that requires correction (anisometropia).
A comprehensive eye examination at Edgbaston Eye Consultants by a doctor will diagnose what is affecting your ability to see well. Once this is done, we will arrange for the best correction of your vision to suit your lifestyle whether it is glasses, contact lenses, a vision therapy program, or surgery that will help improve your vision. If the reduced vision is due to an eye disease, you may be prescribed ocular medication or another treatment.
