Abstract: A corneal surgical apparatus for forming a flap in a cornea, includes: a blade unit including a blade, and an identification information communicating portion that transmits identification information; a head portion that holds the blade unit detachably; an oscillation mechanism portion that oscillates the blade unit, which is held by the head portion, in a direction of a width of the blade; a receiving portion that receives the identification information transmitted from the identification information communicating portion; a storage portion that stores the identification information; and a control portion that collates the identification information received by the receiving portion with the identification information stored in the storage portion, and controls the driving of the oscillation mechanism portion based on a result of collation.

Abstract: In a corneal surgical apparatus for incising a cornea of a patient's eye in a layered form, a blade is movably supported to a main body for lateral oscillation and rectilinear movement. Discrete motors are located within the main body for the lateral oscillation and the rectilinear movement of the blade, respectively. One of the motor is coupled to the blade through a feed screw, an attaching member threadingly engaged with the feed screw, and a hollow connecting member connected to the attaching member, whereas the other of the motor is coupled to the blade through gears, a spline shaft rotatably supported by the inside of the hollow connecting member and non-rotatably but slidably connected to one of the gears, and a converting mechanism for converting the rotation of the shaft to the lateral oscillation of the blade.

Abstract: A polyamide resin composition comprising 100 parts by weight of a polyamide resin, from 0.01 to 100 parts by weight of a liquid-crystalline resin, and from 0.01 to 5 parts by weight of an acid anhydride all the time has good fluidity even when it is left for a relatively long period of residence time in a cylinder of a molding machine while it is molded, and has good moldability. The amount of cushion resin needed for molding the composition fluctuates little, and the failure such as cobwebbing in molding the composition is reduced. The moldings of the composition have good impact resistance and good outward appearance. The composition is most suitable to producing box-type moldings with thin-wall parts.

The suction ring has an opening from which the cornea of the patient's eye is projected. An applanating portion is provided, which has a flat side abutting against the cornea of the patient eye projected from the opening of the suction ring. A blade is supported movably along said suction ring in a space defined between the suction ring and the flat side of the applanating portion. A projection is associated with the blade to increase the space as the blade incises the cornea.
