First let me preface this by saying that I am neither a resident or practicing ophthalmologist. Instead, I am a 4th year medical student that has done several ophtho rotations.
In my humble opinion, ophthalmology is one of the surgical specialties that allows you to tailor your eventual practice to suit your own needs. It has been my observtion that certain surgeons who enjoy surgery simply have a higher surgical volume than those who like a mix of surgery and clinic time.
It seems that fellowship trained surgeons in retina-vitreous and occuloplastics have a higher surgical volume than the general ophthalmologist. Although, I've been told that there are some very high volume refractive surgeons as well. Other sub-specialties of ophthalmology that you may want to look into further are glaucoma, neuro-ophthalmology, and pediatric ophthalmology.
I think the field of ophthalmology in general is technologically based. As to what are the latest advancements in the field? I don't think I am qualified or informed enough to answer that question. I'll leave that up to OphthMuDPhuD or anybody else who might give you the most accurate and up to date information.
I feel that ophthalmology is a great surgical specialty. It allows the surgeon to practice what he/she loves and have time to enjoy life as well.
