[Avodah] eye pains on shabbat

[Eli Turkel]

In a recent daily halacha from ROY they discuss eye pains on shabbat.
The gemara considers it
choleh she-yesh bo sakanah because the eyes are connected to the
heart. The question is that modern  doctors dont know of anu
connections between the eye and the heart.

ROY answers that nishtanu hateva (IMHO dont understand how the anatomy
of man could change - though ROT takes it for granted that changes
happen every few decades). So ROY paskens like chazal against modern
medicine.
Thus, he allows any melacha on shabbat for eye pains including putting
on salves and traveling to the hospital.

R Elyashiv OTOH accepts modern medicine and so is machmir  not to do
any Torah melacha for eye pain unless it is clearly life threatening.
RSZA pasken similar to ROY.
There are also applications to an infant boy with eye problems and
whether to wait and how long for the brit.

The whole discussion reminded me of the Salmon controversy where the
mekilim rely on Chazal and the machmirim say things have changed.
