Mr Lewis Pereira, FRCOphth
Consultant Ophthalmic Surgeon
Mr Lewis Pereira (FRCOphth) is a consultant ophthalmic surgeon specialising in cataract and intraocular lens surgery. He reads over the clinical content on Be Healthy before it is published.
Going through each article, he confirms that the description of cataracts, the phacoemulsification operation, the choice of lens, the risks, and the recovery timeline matches how surgical practice and current guidance see them. His reference points are the Royal College of Ophthalmologists, the American Academy of Ophthalmology, NICE guideline NG77 on managing cataracts in adults, and the NHS, and he flags anything that overstates a benefit or understates a risk.
His reading keeps the writing accurate, but it stops at the edge of your own eyes. It is not personal medical advice, and it cannot take the place of the surgeon who examines you, measures your eyes, and decides with you whether and when to operate. For anything about your particular case, that consultation is where the answers live.
