Brief summary

This is a Phase IIa study to assess efficacy and safety of STN1013600 ophthalmic solution (0.1%, and 0.3 %), twice daily when compared to Placebo in subjects diagnosed with presbyopia. This study will consist of a Screening Period of up to 15 days followed by a 2 Month Treatment Period. After the Treatment Period subjects will be followed for a one-month treatment free period.

Inclusion criteria

* Phakic presbyopic subjects, Male or Female between 47 and 55 years of age. * Distance-corrected near visual acuity (DCNVA) for each eye, as well as for binocular vision, 70 EDTRS letters or worse (equivalent to 0.3 logMAR or worse; or 20/40 Snellen or worse) at 40 cm. To be reconfirmed at Visit 2 (Baseline). * Best-corrected distance visual acuity (BCDVA) for each eye of 85 ETDRS letters or better (equivalent to 0.00 logMAR or better; or 20/20 Snellen or better) at 4 m. To be reconfirmed at Visit 2 (Baseline).

Exclusion criteria

* Secondary cause of presbyopia in either eye as assessed by investigator (e.g., damage to lens, zonules or ciliary muscle, multiple sclerosis, cardiovascular accidents, vascular insufficiency, myasthenia gravis, anemia, influenza, measles). * Any history of ocular surgery (including ocular laser surgery) in either eye or plan of ocular surgery (including ocular laser surgery) during the course of the study. * Prior invasive therapy for presbyopia (e.g., ciliary body electrostimulation, corneal implants).

The summated NAVQ score from initial 10 questions ranged from 0 to 30, where higher score indicates more difficulty with near tasks. The summated NAVQ score is converted to Rasch score which ranged from 0 to 100, with higher values indicating more difficulty with near tasks.
