💬In plain words
What the trial is, and whether it could suit you
Patient: Tear film issues resulting in poor visual outcomes are a major cause of dissatisfaction after cataract surgery. There is no universal best preoperative algorithm for managing the ocular surface prior to surgery.
Industry: Recent advances in tear/cornea imaging and refractive cataract surgery such as multifocal intraocular lenses will be advantageous to patients only if tear film issues can be addressed.
Society: Cataract surgery is the most common ophthalmic surgery done in Singapore and worldwide. Improving vision by attending to tear film problems improves quality of life.
