Two mistakes cost patients the most time. The first is booking a subspecialist directly for a problem that has not been diagnosed yet, and discovering the complaint belongs to a different department. The second is the opposite: sitting with a routine spectacle test for months while a retinal problem quietly progresses. Both are avoidable if you know roughly how eye care is divided up.
Three different people, three different jobs
The titles get used loosely, so start here.
An optometrist measures your vision, refracts you for glasses, fits contact lenses and performs many of the diagnostic tests. They are not medical doctors and do not perform surgery or prescribe treatment for disease. If your only issue is that print has gone blurry and you want a new prescription, an optometrist can complete that visit entirely.
An ophthalmologist is a medical doctor who has done a postgraduate degree in eye disease and surgery. They diagnose and treat conditions, operate, and manage medication. A general ophthalmologist can handle the large majority of what walks through a clinic door, including cataract, glaucoma monitoring, infections, injuries and routine surgery.
A subspecialist is an ophthalmologist who then trained further in one region of the eye, typically for one to two years, and now works mostly on that. Retina, cornea, glaucoma, paediatrics and squint, oculoplasty, refractive surgery. Their advantage is not general skill, it is volume: someone who does one operation several times a week handles the difficult version of it better than someone who does it monthly.
Matching the complaint to the department
You do not need to diagnose yourself. But if you already know your problem, going to the right clinic saves a visit.
- Gradual blur, glare at night, colours dulled, over 55. Cataract clinic. This is the commonest reason people come in, and the assessment is straightforward.
- Sudden floaters, flashes of light, a curtain across part of your vision. Retina, and urgently. Same day, not next week. A retinal tear treated on the day it appears is a laser session. Left for a fortnight it can become an operation.
- You have diabetes. Retina, once a year minimum, whether or not your vision has changed. Diabetic retinopathy is silent until it is not, and by then the damage is structural. Our retina service uses ultra-widefield imaging that captures most of the retina in one shot, which makes this a quick appointment rather than a long one.
- Family history of glaucoma. Glaucoma clinic, from your late thirties. This is the one condition where a family history genuinely changes your risk, and the vision it takes never comes back.
- Redness, watering, foreign body sensation, pain that has lasted days. Cornea and ocular surface, or emergency care if the pain is severe or vision is falling.
- A child, at any age, with a turn in the eye, a white pupil in a photograph, head tilting or trouble reading the board. Paediatric ophthalmology, not an adult clinic. Testing a three-year-old is a different skill, and the treatment window closes around age seven or eight.
- Droopy lid, watering that runs down the cheek, a lump on the lid, sunken or bulging eye. Oculoplasty.
- You want to be rid of glasses. Refractive clinic, for a full workup on corneal thickness and shape. Roughly one in five people who ask turn out to be unsuitable, and it is better to know from the scans than from a sales conversation.
If your symptom is not on that list, or you are not sure, book a comprehensive eye examination. That is what it is for. The examination sorts you into the right department, and it is cheaper and faster than guessing wrong.
What a good consultation looks like
Judging a doctor's skill from one visit is difficult, and the usual proxies are unreliable. Years of experience, waiting-room crowds and online star ratings tell you very little about whether this person is right for your particular problem. A few things do.
- You were examined before you were advised. Any recommendation for surgery should follow a dilated examination and measurements, not a torch and a conversation.
- The explanation used your findings. A doctor referring to your corneal thickness, your pressure reading or your scan is reasoning about you. One who describes the technology in general terms is reasoning about the machine.
- You were told what happens if you do nothing. Every condition has a natural course. A doctor who can describe yours calmly, including the option of waiting, is giving you a decision rather than an instruction.
- Wait and watch was on the table. Small cataracts, mild dry eye and many floaters do not need intervention now. A clinic that never advises waiting is worth being cautious about.
Continuity matters more than the single visit
For a one-off problem, the individual consultation is what counts. For anything long-term, glaucoma, diabetic retinopathy, keratoconus, a child in amblyopia treatment, the more useful question is whether you can keep seeing the same person with the same records and the same equipment.
Glaucoma decisions in particular are made by comparing today's visual field with the one from two years ago on the same machine. Change readings between machines and half that comparison is lost. This is a practical reason to settle on one place early for a chronic condition, rather than moving between clinics for a slightly lower fee.
Geography is part of that. A specialist forty minutes away whom you will actually visit every six months is better than a more famous one across the city whom you will quietly stop seeing after the second appointment.
If you know which department you need, book into it directly. If you do not, book a comprehensive examination and let the findings decide. You can look up who sees which condition on our doctors page, and check timings and locations across our five centres on the branches page.
