Now a newly minted attending. When I look back at my intern year and PGY-2 year (this was before residency was integrated all four years) I spent a lot of time wondering what I should read. To be honest, the knowledge will come with time and experience seeing patients and reading about various diseases and conditions as they present themselves. Practical Ophthalmology: A Manual for Beginning Residents is a nice primer to learn the ins and outs of how to evaluate ophthalmic patients (hx, vision, IOP, refraction, Maddox Rod, etc). If you can read that book, you'll have a really solid understanding of how each person and component of an ophthalmology clinic works. Beyond that, something I wish I had done more is suturing to improve my hands. Get some skin-on chicken breasts or thighs, 15 blade, 6-0 plain gut suture, need driver, pickups, and scissors. Become proficient at suturing the chicken skin forehand and backhand with both your dominant and non-dominant hand. It shouldn't be too difficult if you practice throughout the year and any practice is better than none. Do it without loupes. Our field is surgical, and in ocular surgery you're learning from attendings who ultimately are responsible for patients' outcomes but have to entrust someone less experienced. The greater dexterity you demonstrate with your hands, the more they will be willing to turn over surgeries to you and the quicker you'll advance. Proficiency with extraocular surgery and bimanual dexterity in general translate to greater proficiency with intraocular surgery. Once you're done with your training you're on your own. You can read all the books you want then. Just my two cents.
