The problem is that I can't get the slit lamp close enough to put things in focus when using a 3 or 4 mirror lens. The laser is mounted on the front of the slit lamp and I can get things almost in focus as I edge it forward, but inevitably the front of the laser apparatus ends up hitting the lens and putting pressure on the pts eye. I usually do the exam with my glasses off. My RX is approximately -2.50 + 2.50 @ 90 ou. I have no trouble doing normal exams at the slitlamp with my glasses off. If I wear my glasses it seems there is a lot of glare and so on. I've tried adjusting the oculars to -1.25 or so to see if it helps but it doesn't. My partner and the one other person who uses it don't have the same problem. My partner says he has to get pretty close, but not so close that the laser hits his lens. I'm at a bit of a loss and would love to hear any thoughts or suggestions. I've had to cancel a couple of PRPs because I was just unable to get a view because of this.
