Intraocular lens (IOL) replacement surgery is a specialised procedure performed to improve outcomes for patients who experience suboptimal vision following cataract surgery or refractive lens exchange (RLE). While modern IOLs are highly advanced and successful in the majority of cases, studies show that 1–2% of patients may require lens replacement due to refractive errors, residual astigmatism, or issues like glare, halos, or poor contrast sensitivity.
At London Cataract Centre, we specialize in addressing these issues with advanced diagnostics, individualized care, and surgical expertise to ensure your vision is optimised to its full potential.
Piggyback IOLs offer a less invasive alternative to full lens replacement. In this procedure, a secondary lens is implanted in front of the original IOL rather than removing it. This technique is particularly beneficial for fine-tuning refractive outcomes or addressing residual issues such as high myopia, hyperopia, or astigmatism without replacing the existing lens.
Piggyback IOLs can correct vision problems with minimal surgical intervention and are ideal for patients whose initial IOL placement is otherwise stable.
While cataract and RLE surgeries boast high success rates, certain factors can lead to suboptimal outcomes:
Incorrect lens power or incomplete correction can result in ongoing vision problems such as nearsightedness, farsightedness, or astigmatism.
Some patients opt to upgrade their IOLs to more advanced lenses (e.g., Enhanced Monofocal, EDOF, or Multifocal) to meet their evolving vision and lifestyle requirements.
Despite advances in technology and precision techniques, around 1–2% of patients worldwide may require additional procedures due to:

A very friendly experience from beginning to end. The staff were great and the consultant Mr Hamada was excellent at easing any fears I had. Surgery was painless and quick, staff were very reassuring. Would certainly recommend this clinic to anyone who has cataracts and decides on RLE treatment.
Just had my lens surgery with Dr Hamada. I was very nervous on the day of surgery as I was having both my eyes done on the same day. But there was no need it went very smoothly and very happy with my new eyes.
All I can say is WOW, WOW WOW. I am writing this overwhelming endorsement 48 hours after having RLE in both eyes, pain-free with better than 20/20 vision. For those of you doing your research, I can absolutely confirm the RLE procedure is pain-free in Mr Samer Hamada’s miracle hands… THANK YOU SO MUCH…
