A lens will last ten years or more - so get a good one! They get good prices on EBay, so you can always sell and move on. 90ds is what everyone goes for-there is not much difference with the wide angle:its heavier though. 66ds gives easy sizing - takes lots of practice and is my general use favourite. My other is a standard 90ds.

Don't ever forget great hygiene - so clean the slitlamp and yr hands between each patient.

Its best learned on undilated pupils - after learning - then using a mydriatic = its a breeze and you will have good technique already.

It must be done in a darkened room. The plan is to keep the patients pupil as unconstricted as possible-so go as dark as possible.

Keep talking and explaining all the time = it will help your patient relax and forms a conversation that will help if you do see any pathology. Explaining what you are seeing will help you to remember the details for writing your notes.

Keep the lens and the slit lamp paraxial with the patients pupil.

We will upload a guide to calibrate the slit lamp to allow measurements of the optic disk, from the 1mm slit.

Medium brightness of the slit lamp is all that is needed: contast reduces if you slam the brightness up high. Also, if brightness is very high - you can't vary the brightness up and down to gain an extra tool!

Start using low mag. 1mm slit high and 1/2 mm. wide.

Start by looking at the disk you should be bang on it - if you have lined up properly and the patient is looking at your ear (right ear for examiniing right fundus) or a fixation target on the wall - I use a small testing chart.

Keep the light within the disk - its the blindspot and the pupil will relax even more. fine tune the clarity and then analyse the disk. Then look around..
