The co-ordinated growth of the eye to reach emmetropia is dependent on clear visual input.
However, I hypothesize that the eye is incapable of such detection and will use a trial and error system to reach emmetropia.
Slade reported that 95% of the patients with good pre-operative visual acuity targeted for emmetropia (zero postoperative correction) had uncorrected visual acuities of 20/40 or better and that 57% had uncorrected visual acuities better than their best corrected visual acuity preoperatively.
5 diopters of needing no additional correction (emmetropia) and 80% of the patients were within one diopter of emmetropia.
In this context, emmetropia can be taken to mean a very small range of refractive errors around low hypermetropia.
