Overview

Design the geometry and select the materials of a range of contact lenses then test their optical power before and after the fitting process. This is a self-funded project open to UK and international applicants.

About this opportunity

Soft contact lenses are medical devices largely used to correct the eye refractive error for more than 125 million people worldwide. Unlike spectacle lenses which are used in conventional glasses, soft contact lenses should be designed to fit the user’s eye beside being able to correct his vision. During the fitting process, the surface of the contact lens deflects to fit the eye shape, therefore, the optical power of the soft lens on-eye differs from the one originally manufactured and tested off-eye.

In this project, the student will design the geometry and select the materials of a range of contact lenses then test their optical power before and after the fitting process. The product design process will be carried out by a MATLAB software code, however, the process of fitting contact lenses to human eyes will be simulated by FE-BIO finite element software where the 3D change in the shape of a contact lens can be monitored and recorded. The student will then use knowledge gained from this exercise to obtain correction factors that can be used to take the deflection of soft contact lenses in account when design contact lenses.

Who is this opportunity for?

This project is open to self-funded UK and international applicants.

Fees and funding

Your tuition fees, funding your studies, and other costs to consider.

Tuition fees

Fees stated are for the 2025-26 academic year.

  • Full time UK fee: £5,006 per year
  • Full time international fee: £31,250 or £24,600 per year.*

Fees apply to academic year 2025/26.

* Please note: if you’re an international student undertaking a PhD within the Faculty of Science and Engineering, the fee you pay will reflect the nature of your research project. Some research projects incur a higher fee than others, for example if you’re required to undertake laboratory work. You’ll be informed of the fee for your intended PhD in your offer letter.

Additional costs

We understand that budgeting for your time at university is important, and we want to make sure you understand any costs that are not covered by your tuition fee. This could include buying a laptop, books, or stationery.

Find out more about the additional study costs that may apply to this project.

Funding your PhD

This is a self-funded opportunity. You may need to apply for external funding to cover tuition fees and living expenses.

If you're a UK national, or have settled status in the UK, you may be eligible to apply for a Postgraduate Doctoral Loan worth up to £30,301 to help with course fees and living costs.

There’s also a variety of alternative sources of funding. These include funded research opportunities and financial support from UK research councils, charities and trusts. Your supervisor may be able to help you secure funding.

My qualifications are from United Kingdom.

Scholarships and bursaries

We offer a range of scholarships and bursaries that could help pay your tuition fees and living expenses.

Duncan Norman Research Scholarship

If you’re awarded this prestigious scholarship, you’ll receive significant funding to support your postgraduate research. This includes full payment of your PhD fees and a cash bursary of £17,000 per year while you study. One award is available in each academic year.

John Lennon Memorial Scholarship

If you’re a UK student, either born in or with strong family connections to Merseyside, you could be eligible to apply for financial support worth up to £12,000 per year for up to three years of full-time postgraduate research (or up to five years part-time pro-rata).

Sport Liverpool Performance Programme

Apply to receive tailored training support to enhance your sporting performance. Our athlete support package includes a range of benefits, from bespoke strength and conditioning training to physiotherapy sessions and one-to-one nutritional advice.
