How to Prepare for Your First Ophthalmologist Appointment

Your eyes are among the most complex organs in the body, and an ophthalmologist appointment can cover everything from a routine prescription update to glaucoma screening, retinal assessment, or pre-surgical evaluation. Whether you have been referred by your optometrist or GP, or are attending a public eye clinic in Singapore, Malaysia, or Australia, knowing what to expect — and what to bring — ensures you get the most from your visit.

1. What is the difference between an optometrist and an ophthalmologist?

This is one of the most common points of confusion in eye care:

• Optometrist — A health practitioner (not a medical doctor) who performs eye examinations, prescribes glasses and contact lenses, and screens for common eye conditions. In most countries, optometrists can prescribe certain eye drops.
• Ophthalmologist — A fully qualified medical doctor who specialised in eye disease and surgery. Ophthalmologists diagnose and treat eye conditions medically and surgically — including cataracts, glaucoma, retinal detachment, diabetic retinopathy, and corneal disease.
• Orthoptist — A specialist allied health professional who assesses and treats binocular vision problems, squint (strabismus), and amblyopia (lazy eye) — particularly in children.

If your optometrist has flagged a concern requiring further investigation, or your GP has referred you for a specific eye disease, you are likely seeing an ophthalmologist. In public hospitals in Singapore (SGH, SNEC) and Australia, you may be seen by a registrar supervised by a consultant ophthalmologist.

2. What information should I bring to my ophthalmologist visit?

Prepare the following before your appointment:

• Current glasses and contact lenses — Bring all pairs you actively use, including reading glasses. The ophthalmologist may want to check your current prescription.
• Contact lens prescription and brand — Note the brand, base curve, diameter, and power.
• List of all eye drops and medications — Include any prescription eye drops, lubricating drops, antihistamine drops, or systemic medications that can affect eye health (steroids, hydroxychloroquine, tamsulosin).
• Referral letter — Your GP or optometrist referral letter contains clinical details that help the ophthalmologist prioritise their assessment.
• Family history — Glaucoma, macular degeneration, and retinal detachment have hereditary components. Flag these if relevant.
• Duration and description of symptoms — When did your vision change? Is it one eye or both? Blurry, distorted, floaters, flashes, or pain?

3. What eye tests will the ophthalmologist perform?

A comprehensive ophthalmology assessment may include several of the following, depending on your referral reason:

• Visual acuity test — Reading a letter chart (Snellen or LogMAR) at distance and near, with and without glasses
• Refraction — Determining your optimal glasses prescription using a phoropter or auto-refractor
• Intraocular pressure (IOP) measurement — Using tonometry (a puff of air or a contact probe) to screen for glaucoma
• Slit-lamp examination — A microscope examination of the front of the eye (cornea, iris, lens)
• Dilated fundus examination — Eye drops are used to widen the pupil so the retina, optic nerve, and blood vessels can be examined
• Visual field test — Detects peripheral vision loss, important for glaucoma monitoring
• OCT (Optical Coherence Tomography) — A non-invasive scan of the retina and optic nerve, increasingly standard in specialist practice

4. Should I bring my glasses or contact lenses?

Yes — bring both. Your ophthalmologist will want to see how well you see with your current correction. Some tests are performed with glasses on, others without. If you wear contact lenses, you will generally be asked to remove them before certain measurements (corneal topography, biometry) — typically at least 24 hours before for soft lenses, longer for rigid gas-permeable lenses.

If you are attending for a laser eye surgery consultation (LASIK, SMILE, PRK), contact lens wear must be stopped well in advance — usually 1–2 weeks for soft lenses. Your surgeon’s office will advise the exact duration.

5. What questions should I ask my ophthalmologist?

Make the most of your consultation with these targeted questions:

• What is the diagnosis, and how serious is this condition?
• Will this condition affect my driving vision now or in the future?
• Do I need treatment now, or is watchful waiting appropriate?
• What are my treatment options and their risks?
• Should I modify any activities (swimming, contact sports, screen use)?
• Do my children or close relatives need eye screening?
• How often should I have follow-up eye examinations?

6. What should I expect after pupil dilation?

Dilating eye drops take 20–30 minutes to work and cause your pupils to remain enlarged for 4–6 hours (sometimes longer). During this time:

• Near vision will be blurred — you will not be able to read comfortably
• You will be highly sensitive to bright light (sunglasses are strongly recommended)
• Driving is not safe while dilated — arrange a driver or plan to use public transport
• Effects wear off naturally; no reversal drops are routinely given

In Singapore and Malaysia’s climate, the glare from bright outdoor light after dilation can be intense. Pack a pair of wraparound sunglasses in your bag. Wrap-around sunglasses available at pharmacies work well.

7. What should I do after my eye appointment?

• Ask for a printed copy of your visual acuity and any measured pressures or prescription
• Clarify the timeline for starting any new eye drops and the correct instillation technique
• Book follow-up imaging or visual field tests before leaving if recommended
• Update your optometrist with the outcome of your ophthalmologist visit
• In Australia, register your eye health with the National Eye Health Survey or KeepSight (for diabetic retinopathy monitoring)

Recommended Tools for Your Eye Appointment

• Wraparound UV sunglasses — Essential for the journey home after pupil dilation, especially in the bright tropical sun of Singapore or Malaysia.
• Preservative-free lubricating eye drops — Dry eye is extremely common and often diagnosed at ophthalmology visits; having drops on hand is recommended.
• Contact lens travel kit — Keep a spare case and solution in your bag so you can remove contacts easily before examinations.
