Frequently Asked Questions


Navigating specialised eye care can raise many unique clinical, logistical, and aesthetic questions. Below, Mr Kanti Fatania and the Eye Excellence team have compiled clear, detailed answers to help you understand our bespoke prosthetic engineering, specialised lens systems, and clinical workflows in London.

Clinical & Treatment Queries

An ocular prosthesis (artificial eye) is designed to fully replace a missing natural eye following surgical removal, such as an enucleation or evisceration procedure. It is shaped to sit comfortably over an orbital implant.

Conversely, a cosmetic scleral shell is an ultra-thin optical cover worn directly over an existing, non-seeing, or discoloured natural eye to gracefully conceal imperfections and restore facial symmetry without surgery.

For a fully bespoke ocular prosthesis or cosmetic shell, the process typically spans 15 to 20 working days to accommodate precise fit, shape, hand-layering of colours, and gloss.

However, for our international patients travelling from Europe, the Middle East, or Africa, we can explore expediting the process on a case-by-case basis.

Yes. Mr Kanti Fatania utilises a combination of high-definition digital photography, cross-lighting analysis, and hand-painting to perfectly replicate the intricate iris depth, structural colour variations, and unique blood vessel patterns of your companion eye.

No. To ensure absolute tissue safety, optical precision, and long-term comfort, we strongly recommend attending our London clinic in person. Each device must be perfectly contoured to the living topography of your eye socket. While we provide robust virtual consultations and post-care support for global clients, the initial structural impression and final fitting require physical clinical calibration.

Care, Longevity & Maintenance

For adult patients, a premium bespoke prosthesis typically lasts between 5 and 7 years. Over time, while the medical polymer itself remains structurally stable, your underlying orbital tissues and socket geometry will undergo natural, subtle physical shifts.

Children require more frequent replacements to safely keep pace with their natural facial growth.

Always wash your hands thoroughly before handling your prosthesis. Clean the surface using an approved, specialised rigid contact lens cleaner, and rinse meticulously with warm water. Never use regular saline or unapproved chemicals, as they can encourage bacterial growth.

To prevent protein build-up and maintain a glassy, frictionless surface, we recommend a professional clinical polish every 12 to 18 months at our clinic.

A masterfully fitted prosthesis should feel lightweight, comfortable, and entirely natural after a brief initial adaptation period. It should allow your eyelids to blink completely normally and support natural tear distribution.

If you experience persistent irritation, physical pressure, or unusual discharge, it is an indication that the device requires professional modification or polishing.

Logistical, International & Referral Queries

No, a formal medical referral is not strictly required; you can book a consultation directly with our London clinic. However, we maintain a highly collaborative medical network. We work closely with leading NHS trusts, private ocular surgeons, and top-tier ophthalmic specialists across the UK, including trusted clinical partners on Harley Street, allowing us to seamlessly manage your transition from surgery to prosthetic recovery. Should you require support in this regard, please do reach out.

We can provide logistical support for our global clients and direct you onwards to trusted partners, if required. If your prosthesis requires remote technical polishing or structural assessment later on, you can securely ship your prosthesis to our London laboratory via registered global couriers for rapid maintenance and return delivery.
