Cataract surgery is common, particularly for those over $60,$ and is relatively routine today. An intraocular lens $($or IOL$)$ is a tiny artificial lens for the eye. It replaces the eye$$s native lens, which is removed during cataract surgery. Patients can choose several IOL choices $($listed in cost from lowest to highest$)$ to treat additional $($chronic but not severe$)$ vision impairments as a part of cataract surgery based on the severity of these conditions $($i$.$e$.,$ astigmatism$)$ and the price the patient is ready to spend to correct them. Most health plans do not cover advanced IOL alternatives. A research study in $2020$ revealed four distinctive and unique broad categories of healthcare consumers.

Discuss the following

$1.$ Should various promotional and personal messages $($i$.$e$.,$ benefits and hazards$)$ be offered as part of product training by the IOL producer for the different groups as described above?

$2.$ If so$,$ provide examples.
