A stakeholder meeting exploring the ethical perspectives of immediately sequential bilateral cataract surgery Open
Purpose The purported benefits and risks of immediately sequential bilateral cataract surgery (ISBCS) have been well described, yet the procedure remains controversial among UK ophthalmologists. As many of the controversies of ISBCS are un…
