Calculation shows that the first focal plane is near the tip of the cone, from which the optical pathway continues as a crystalline tract. At the distal end of the crystalline tract, 3 µm in diameter, the four cone cells enclose the proximal tip of the corneal cone; at the proximal end they enclose the distal tip of...[Show more]
