Ophthalmology lenses and indirect

This is a question for Dr. Doan and other ophtho residents and practicing ophthalmologists. What lenses do you recommend a starting ophthalmology resident should purchase? Also which indirect is better: a new keeler or heine?

Thanks

I recommend starting out with a 90D and 20D. If you have extra $$$, then get a 60D or 78D. Otherwise, a 90D and 20D is all you need to start.

We use the Heine Omega 180 in our clinics at Iowa, and I like them:



Good luck!

The Heine 180 that I ordered came in the mail a few days ago. In addition to making me even more excited about starting my residency in a few days, I'm also somwhat confused.

The oculars come with +2D lenses installed standard with a pair of plano lenses to substitute if desired. Am I missing something or should someone like myself (with 20/20 vision) simply insert the plano lenses? Is there any advantage to +2D views, ie. with the focal point of a 20D indirect lens?

Thanks for the help.

I have about 1 year before I need lenses, etc. Is there a website or book that anyone recommends that I can learn about the qualities of the various lenses and indirects? I am comfortable with the 90D, but I like the expanded view of the superfield or 78D. I just don't know anything about brands, services and I really don't know much about indirects at all. Thanks.

I like the 60D. It gives nice magnification. rarely use the 90D anymore; even in undilated eyes, you can see alot with the 60D.
However, the most popular choice is 90D and 20D. Before investing in a 60D, try it out first.
if you already have a 90 and a 20, I'd suggest getting a gonio lens before getting another indirect lens.

The +2 lenses are for people who are approaching presbyopia or latent hyperopes who need a little extra plus. A young person with excellent accommodation doesn't need them.

I would recommend the spectacle mounted Keeler Indirect, because it is much more portable, when you want to visit patients in intensive care, or the emergency department for example. But it really is a matter of personal preference - Heine make excellent stuff too.

Re lenses: there was a really detailed discussion about these 9-12 months ago. It would be worth searching & reading if you want to know more about the advantages of various lenses.

While I agree with the prior posts that the 90D and 20D are the only basic lenses that are needed, if I were to start over, I would pick the following:

Volk Pan Retinal 2.2 - After using my 20D for over a year, I used our Retina Fellow's 2.2 lens and fell in love with it. It provides nearly the same mag as the basic 20D lens but provides a larger view, similar to the 30D lens. It has a great image that provides a better view of the extreme periphery.

Volk Super 66 - I prefer this lens over the 90D lens. It is similar to the 78D lens in image mag but provides a little better clarity. Again, provides a little more than the basic lens. This lens is great for examining the macula and disc.

Volk Super Vitreofundus - If I were to buy a third lens, it would be this one which is similar to the 90D but provides a very wide field of view and slightly smaller mag. I used this for a great widefield view of the posterior pole through a non-dilated pupil. Another option is the Super Pupil.

Just my take. In general, talk to the residents at the training program that you will be attending. Some programs have attendings that recommend certain lenses over others. Good luck.
