Slit Lamp and BIO Lenses

[yetbun12]

I'm looking for advice on purchasing my first set of slit lamp lenses. As of right now, we are required to purchase a 20D (or other equivalent BIO lens) and a 90D/super field. I am aware of the specs of the different lenses and I'm leaning towards the digital clear field for my BIO lens and the super field for my 90D.
1. What is your preference between 90D vs super field and why? I know 90D has better small pupil capability but I like the wider field of view that the super field offers. I'm not sure which would be better for general optometry practice. I am also planning on purchasing a super66 or a 78D in the future for a more magnified view.

2. Has anyone tried the 20D and the digital clear field BIO lens? Based on the stats the pan retinal 2.2 is quite similar to the digital clear field, but the digital clear field has a slightly higher magnification and smaller lens size. Is there any down side to going for the digital clear field instead of the standard 20D?

Appreciate any comments!! thanks

only complaint with digital lenses (for me) was I would get a lot of glare.I prefer the pan retinal 2.2 to digital though its a bit bigger. superfield is pretty cool but I find I always use my 90D

I agree with this^ .. Also, I'm pretty sure you have to use the 90D on boards for undilated pupil? Oh.. and if you have the option of ordering colors, the darker the better. I've had a lot of classmates have issues with the gold, silver, and light pink color on their 90D

90D and dilated pupil unless the changed its and you are correct the gold and silvers produce a lot of glare....always go for a darker lens
