28.5 Dressings and Shields, Prosthetics, Legal Forms, Referrals & Reimbursement Support
Key Takeaways
- A pressure patch immobilises the lid and is never used on a contact-lens-related abrasion or a suspected open globe.
- A rigid shield protects without pressure and is the correct dressing for a suspected open globe and for post-operative nights.
- An ocular prosthesis is cleaned over a soft surface, handled minimally, and professionally polished at intervals.
- Vision forms for driving and government benefits require accurate, measured data and the prescriber's signature.
- Referrals to low vision services, rehabilitation agencies and support organisations must be documented like any other clinical action.
Dressings, pads and shields
| Device | Purpose | When used | When avoided |
|---|---|---|---|
| Pressure patch | Immobilises the lid over the cornea to promote epithelial healing and reduce pain | Selected large abrasions, after some procedures, per clinician direction | Contact-lens-related abrasion (traps organisms — never patch), infection, suspected open globe, patients who need both eyes for mobility, monocular patients |
| Light dressing / pad | Absorbs discharge, protects | After some minor procedures, after chemical injury per direction | Where a seal would trap discharge |
| Rigid shield (Fox shield or improvised) | Protects without pressure | Suspected open globe, post-operative nights, protecting a healing eye from rubbing | Never a substitute for a pad where absorption is needed |
| Bandage contact lens | Protects the epithelium and relieves pain while allowing vision | Recurrent erosion, persistent epithelial defect, post-refractive surgery, bullous keratopathy | Applied and managed by the clinician |
Applying a pressure patch: the patient's eye must be closed under the pad — a pad over an open eye abrades the cornea. Use two pads, the first folded, tape firmly from the mid-forehead diagonally to the cheek so the lid cannot open, and confirm by asking the patient to try to open the eye and checking that no lash movement is felt.
Applying a rigid shield: rest the shield on the bony orbital rim — forehead above and cheek below — so that no pressure whatsoever reaches the globe. Tape from forehead to cheek. If a commercial shield is not available, the bottom of a paper cup cut to size is the classic improvisation. Never pad a suspected open globe, because the pad transmits pressure.
Removing a dressing: loosen the tape toward the wound rather than away from it, support the skin, and inspect the eye before the patient does. Warn about temporary blurring from ointment.
Post-operative shield instruction: wear at night for the period specified, do not remove to check the eye, do not rub, and return for increasing pain or reduced vision.
Ocular prosthetics
An ocular prosthesis is a custom-made acrylic shell fitted over an orbital implant or into an anophthalmic socket. Instructing patients in its care is a named blueprint task.
Care instruction:
- Wash hands before handling.
- Work over a soft surface — a folded towel over a closed sink — because a dropped prosthesis chips, and a chipped prosthesis abrades the socket.
- Handle as little as possible. Current advice generally favours infrequent removal, because repeated removal irritates the socket and increases discharge. Many wearers remove it only every few months or as advised.
- Clean with mild soap and water or a recommended solution, rinse thoroughly, and never use alcohol, solvents or abrasive cleaners, which damage the acrylic surface.
- Lubricate as advised for comfort.
- Professional polishing at intervals, commonly annually — surface deposits and micro-scratches cause discharge and discomfort.
- Never sleep with it out unless advised, because the socket can contract.
- Report increasing discharge, pain, a change in fit, or a loose or rotating prosthesis rather than simply cleaning more often.
Removal and insertion are taught with a suction cup or by finger technique, always over a soft surface, and the patient should demonstrate before leaving.
Psychological care matters. Recent eye loss is a bereavement as well as a functional change. Acknowledge it, avoid the word "fake," allow time, and offer support-group information. Also counsel about monocular adaptation: loss of stereopsis affecting pouring, stairs and driving; a reduced field on the affected side requiring more head turning; and the absolute importance of protective polycarbonate eyewear for the remaining eye, full time.
Legal forms for patient benefits
The blueprint names "complete legal forms for patient benefits (motor vehicle, government, etc.)." The technologist's role is to supply accurate measured data; the prescriber signs and takes clinical responsibility.
Common forms:
| Form | Typical data required |
|---|---|
| Driving licence vision report | Best-corrected acuity each eye and binocularly, visual field extent, diplopia, any conditions affecting driving |
| Certificate of visual impairment / legal blindness | Best-corrected acuity in the better eye, visual field diameter, diagnosis |
| Disability benefit forms | Acuity, fields, functional impact |
| Occupational and pre-employment vision standards | Acuity, colour vision, stereopsis, field |
| School or sports clearance | Acuity, correction, protective eyewear requirement |
| Insurance and medico-legal reports | Whatever the specific request states |
Rules:
- Only record what was measured, on the date it was measured. Never copy forward a previous result onto a legal form.
- Use best-corrected acuity unless the form asks otherwise, and state whether correction was worn.
- State the method — which chart, which perimeter, which strategy.
- Leave nothing blank; write "not tested" rather than leaving a field empty.
- The prescriber signs. A technologist does not sign a clinical certification.
- Release only with the patient's written authorisation, or where a statutory duty applies.
- Keep a copy in the record and note the date it was sent and to whom.
Driving standards vary by jurisdiction and change, so verify the current local requirement rather than quoting a remembered number. Where a patient's vision may not meet the standard, the clinician — not the technologist — has the conversation, and any duty to notify a licensing authority is discharged according to local law and clinic policy.
Referrals
Provide patient referrals as appropriate is a blueprint item. The referrals an ophthalmic clinic most often makes:
| Referral | For |
|---|---|
| Low vision service | Any patient whose best-corrected vision limits daily function — do not wait for legal blindness |
| Orientation and mobility training | Peripheral field loss, mobility difficulty, recent severe loss |
| Occupational therapy | Adapting home, work and daily tasks |
| State or national vision rehabilitation agency | Benefits, training, equipment, employment support |
| Talking book and accessible media services | Reading access |
| Support and patient organisations | Peer support and condition-specific information |
| Social work | Transport, finances, home support |
| Family doctor or specialist | Newly discovered hypertension, diabetes, suspected giant cell arteritis, carotid disease |
| Genetic counselling | Hereditary retinal and optic nerve disease |
Document every referral: to whom, for what, on what date, and what the patient was told. An undocumented referral is indistinguishable from one that was never made, and referrals are frequently the item that falls through.
Do not wait for a threshold. The commonest failure is deferring a low vision referral until the patient is legally blind. Functional benefit begins far earlier, and early referral maintains independence rather than restoring it after loss.
Medication reimbursement and cost support
The blueprint names "provide patient counselling and assistance for medication reimbursement programmes." Cost is a leading, under-discussed cause of non-adherence, and patients rarely volunteer it.
Ask directly and without judgement: "These drops can be expensive. Is cost going to be a problem for filling this?"
Options to know about:
- Generic substitution where clinically appropriate — the prescriber decides
- Manufacturer patient assistance programmes and copay cards
- Non-profit and charitable assistance foundations
- Government and insurance formulary alternatives — a different agent in the same class may be covered
- Prior authorisation support, where the clinic supplies the documentation the insurer requires
- Pharmacy price comparison, which can vary substantially for the same drug
- Fixed combination products, which reduce both cost and drop burden
- Larger bottle sizes or 90-day supplies where permitted
The technologist's role is to identify the barrier, inform the clinician so a therapeutic alternative can be considered, supply the paperwork the programme requires, and document what was arranged. A patient who leaves with a prescription they cannot afford has effectively not been treated.
