1. A kit for aligning an ocular implant with a visible ocular feature of an eye of a patient, comprising:
- a pharmacologic agent configured to be applied to the eye and to increase the correlation between the location of a visible ocular feature and the line of sight of the eye; and
a mask comprising a small aperture having a mask axis and a visible mask feature, the visible mask feature being configured to be aligned with the visible ocular feature to substantially align the mask axis with the line of sight.

Abstract
A method increases the depth of focus of an eye having a line of sight. A pharmacologic agent is applied to the eye to cause a reduction in the size of the pupil of the eye. The pupil is aligned with a visible feature of a mask comprising a pin-hole aperture. The pin-hole aperture is centered on a mask axis. The alignment causes the mask axis to be substantially aligned with the line of sight of the eye. The mask is applied to the eye of the patient while maintaining the alignment of the visible feature of the mask and the pupil.

8. A mask configured to be implanted in a cornea of a patient to increase the depth of focus of the patient, the mask comprising:
-
an anterior surface configured to reside adjacent a first corneal layer;
a posterior surface configured to reside adjacent a second corneal layer;
an aperture configured to transmit along an optic axis substantially all incident light;
a substantially opaque portion surrounding at least a portion of the aperture; and
at least one window portion formed in the opaque portion through which a visible ocular feature of an eye can be observed to facilitate alignment of the mask with the line of sight of the patient'"'"'s eye. - View Dependent Claims (9, 10, 11, 12)

13. A method of increasing the depth of focus of an eye of a patient, the eye having a cornea and a line of sight, the method comprising:
-
applying a pharmacologic agent to the eye to cause a reduction in the size of the pupil of the eye;
aligning with the pupil a visible feature of a mask comprising a pin-hole aperture centered on a mask axis, the alignment of the visible feature with the pupil causing the mask axis to be substantially aligned with the line of sight of the eye; and
applying the mask to the eye of the patient while maintaining the alignment of the visible feature of the mask and the pupil. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method for increasing the depth of focus of a eye of a patient, the eye comprising a visible ocular feature and a line of sight, the method comprising:
-
treating the eye to increase the correlation between the location of the visible ocular feature and the line of sight; and
applying to the eye a mask comprising a pin-hole aperture having a mask axis such that a visible feature of the mask is aligned with the visible ocular feature and the mask axis is substantially aligned with the line of sight. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. A method for correcting vision, comprising:
-
performing a LASIK procedure;
treating the eye to alter a visible ocular feature;
applying the mask to the eye such that a visible feature of a mask is aligned with the visible ocular feature, the mask comprising a pin-hole aperture having a mask axis. - View Dependent Claims (41, 42)
