Both lenses are work horses and provide an excellent balance of field of view and magnification. The 20D is a trusted classic, however, if you are looking for an enhancement, the Pan Retinal lens does provide 22% greater field of view while still providing a good balance of magnification. The Pan Retinal 2.2 also has a closer working distance (10 mm less than the 20D), so you may find it easier to handle depending on your preference.
Many doctors choose to use a 28D or 30D lens for patients with small pupils. The 30D offers slightly more field of view with ever so slightly less magnification
Yes, all our Classic BIO lenses are compatible with lasers and can be used for LIO (Laser Indirect Ophthalmoscope). The 28D or 30D are preferred for ROP. The reusable BIO lenses are compatible with ETO for sterilization before treatment (but not autoclavable). If you prefer to use an autoclave, only the autoclavable 20D ACS or 28D ACS lenses can be used. You can also choose to use single use 20D or 28D lenses for LIO procedures.
You can clean non-contact lenses with lukewarm or distilled water and gentle soap. Dry with a lint-free cotton cloth, moving in a clockwise direction to avoid loosening the lens ring. Avoid high water pressure and microfiber cloths. You can always refer to our Cleaning & Care Guide or the lens IFU for more detailed instructions.
