I am compelled to weigh in. There are a lot of threads revolving around income in ophthalmology. General vs cornea vs retina, and citing compensation surveys. I will weigh in with my experience, the math, and maybe a broader perspective. I will be as honest as possible.
Me: general ophthalmologist (high volume cataract practice), 10 years in practice, hung out a shingle and started from scratch (didn't pay myself for 9 months). Two new associates now to help with work load, I work 4.5 days/week. Total pre-tax income was 1.1 million. 850K from practice, 150K from ASC ownership, 100K from emergency coverage at local hospital. Hopefully more next year as associates ramp up. I certainly would not call this fabulously wealthy, but it is certainly enough to have what I need and save a lot.
The thing to remember when trying to rationalize why one ophthalmologist makes more than another is volume. The bulk of your income, initially, will come from your practice. Generally speaking, I get paid the same amount to do a cataract as a guy in NYC or Fargo. Retina guys all get paid the same amount per injection or membrane peel. The guys who make more, do more. I know ophthalmologists who make 250K/year. They also see fewer patients and do 5 cases/week. That works for them. I know a cataract/lasik guy who makes >2 million every year. He is like a machine. Once again, volume. If you want to work hard, see a lot of patients, and do a lot of surgery, you will make a lot of money. This is just math. I do not mean to over-simplify this. The practice managers will factor in all of the other expenses that affect bottom line. However, they will also point out what a significant impact something as simple as doing 3 more cases/week, or seeing 3 more patients/day will have on your bottom line at the end of the year. This scales very nicely.
What about other stuff? Passive income is very important. This field offers a lot of ways to augment your practice income as your practice matures. They take time to implement but are very worth it. These things are what seems to make the difference between the guys to do "well", and the guys who kill it. Examples:
1) ASC ownership. You need to do this, period. The ROI on these, if well run, will beat almost anything else you can put your money in.
2) Clinical trials. Can be difficult to become an established center, but can be very lucrative and offers an alternative to just seeing patients.
3) Own your building/office. Takes time, but instead of paying a landlord every month, the practice pays you rent. Good for retirement
4) Associates. You pay your junior associate 250K/year. He collects 600k for the practice. Costs you 50K in overhead for him. You make 300K/year off his work. This also scales nicely.
5) ER coverage. Depending on the area, some hospitals pay specialists to cover their EDs.
6) Speaking/consulting. Not for everyone, and can time to establish yourself as an authority.
7) Non-reimbursed services. Lasik, premium lenses, botox. Self-explanatory.
8) Optical shop.
Not all of these apply to every location and practice arrangement, but can add a lot to your income. The people you think of as the most successful likely do many of these things.
Take home message: stop stressing. This is a great (the best?) field in medicine. If it is money you are after, it's there, but you will need to work for it. Do a fellowship if you want, but not because you see it as the road to riches. You do not need one to thrive. There are a hundred other factors to consider, but I will save those for another post. On a side note, I automatically like anyone who references Karate Kid. Strike first, strike hard, no mercy, sir!
