What is it about?
Cataract surgery is the most common ophthalmic surgery in the world. For best results, a good tear film is necessary both pre and post operatively. We review the steps that doctors can use to assess and treat the tear film in order to ensure good post operative outcomes.

Why is it important?
Poor tear film preoperatively results in inaccurate biometry, so that the incorrect intraocular lens may be inserted during surgery. When the tear film is disturbed, patient's vision is not satisfactory postoperatively, even if the surgery is technically successful. This results in poor patient satisfaction.
Perspectives
This is a hot topic for physician education. There is now a trend of inserting non-standard intraocular lenses such as multifocal and toric lenses which are more expensive and much more demanding in terms of the optics of the eye. The benefits of these lenses are obliterated in the presence of poor tear film.
