You need it. I was unmotivated about research too, but as I'm getting more involved as an M4 I'm realizing there's not much to it. I did 2-3 small projects which only led to posters (not enough data) where I gathered the data, analyzed it with excel, and then made a poster with PPT and I was doing it wrong. The way you find research is somehow get in touch with the Optho department. They'll mention some study they're doing which involves manually collecting data from an EMR (not sure why EMRs don't have data-mining options in today's age of information) and offer to be their scut monkey. Register for the EMR, do the stupid HIPPA things, and then go through the charts and input the required variables into a spreadsheet (being good at Excel helps). If you do that in a timely manner, they'll be impressed and either give you more or offer you a larger role in writing the manuscript, etc. It would have been hard to do this as a M1-3 in retrospect because I'd probably have procrastinated with other important stuff to do, but looking back what I would have done differently is allocated the least hour of work to doing this every single day and I might have knocked out lots of chart reviews. Don't worry about the subject of the project either, it doesn't have to be ground-breaking, it could be something as simple as looking to see if patients who had cataract surgery had X, Y, Z complications. From that you can look at the EMR and find how many days it took for those complications to emerge, which type of technique/surgery was associated to those complications, etc. Anyways, that's usually what the attendings/fellows figure out, you just have to do the scut.
Also, the ideal time to get started on this is during summer break. For now, besides trying to secure a summer position (time to do that is now) just focus on classes. The ideal position would be one where you're basically paired with an Optho physician and you can spend some time shadowing and then some time doing chart reviews. Don't worry about past experience being a selection criteria, just apply!
