Law et al1 state that there are conflictingreports on the effect of the scleral expansion procedure on reducing intraocularpressure (IOP). Law and colleagues confuse the scleral expansion procedure(incisions combined with a scleral expansion plug) with the scleral expansionband (SEB).
Of the 4 methods presently being used to increase the distance betweenthe crystalline lens equator and the ciliary muscle to treat presbyopia, onlythe SEB has been documented to lower the IOP in ocular hypertension and openangle glaucoma. In addition to the SEB, the techniques exclusively developedfor treating presbyopia include (1) scleral incisions and/or ablations, (2)incisions combined with a scleral expansion plug, and (3) sulcus rings (AnneauPresbytie or Presbyopia ring).
