A system and a method of cast molding toric contact lenses permits aligning first and second mold sections at multiple rotational positions. Each mold section includes a set of alignment features that engage with complementary alignment features on the other mold section.

Cast molding toric contact lenses

A casting mold is provided for forming a biomedical device including an ophthalmic device such as a contact lens. The casting mold includes an anterior mold section and a posterior mold section, wherein one of the mold sections includes a plurality of radially extending ribs and the remaining mold section includes an annular shoulder for engaging an outer end of the ribs to define a mold cavity.

A blade holderincludes a bottom surfacefor attachment to a blade. A top surfaceinterfaces with a drive-pinof a microkeratome. A drive slotis formed in the top surfacefor engagement with the drive-pinfor allowing oscillation of the blade holder. A plurality of stepsare formed in the top surface, and rise from the drive slottoward at least one sideof the blade holder

Stepped microkeratome blade holder

A method is provided of forming a biomedical device in a casting mold which has an anterior mold section and a posterior mold section, wherein one of the mold sections includes a plurality of radially extending ribs and the remaining mold section includes an annular shoulder for engaging an outer end of the ribs to define a mold cavity. The method includes engaging the mold sections along a peripheral seal of the mold cavity and a plurality of circumferentially spaced contact points on a shoulder of one of the mold sections. Cured excess material bonds to the ribs of the one mold section and provides repeatable retention and location of the excess material after formation of the biomedical device.

A cutting blade assemblyincludes a ceramic bladewith a forward cutting edge. A lower portionof a blade holderis formed of ceramic and is integral to ceramic blade. An upper blade holder portionis attached to the lower blade holder portion, such that the upper blade holder portionis structured for engagement with a microkeratome oscillation mechanism

Method and apparatus for molding an IOL comprising first and second mold halves each having an optic forming surface and haptic forming surfaces which together define a mold cavity in the shape of the IOL to be molded therein when the mold halves are assembled together. An injection port is formed and connects to one of said haptic forming surfaces or the optic forming surface wherethrough a polymerizable material is injected into the mold cavity. A venting port is formed and connects to another haptic wherethrough air escapes from the mold cavity as the polymerizable material is injected through the injection port.

Apparatus and method for making intraocular lenses

Method for removing unwanted excess material from a mold section is particularly adapted for removing a monomer ring adhered within a reservoir of a female mold section used to mold a contact lens. The invention involves piercing the monomer ring and rotating the piercing members (e.g., annularly spaced pins) relative to the mold section whereby the monomer ring is sheared from the mold section to which it was adhered while the molded lens is left intact in the mold section.

Methods for separating material from a mold surface

Apparatus for clamping together contact lens molds having a polymerizable liquid monomer disposed therebetween includes a plurality of clamping assemblies each having a linearly translatable shaft member mounted to a contact lens curing table. A common mold clamp release assembly is provided through which each mold clamping assembly passes, thereby ensuring that each mold set is subjected to the same clamping and release profile. Additionally, the amount of clamping force of each clamping assembly may be individually adjusted by way of an adjustable nut mounted to the shaft member which, thereby, controls the amount of force delivered by the shaft member to the contact lens molds being clamped.

A method and apparatus for practicing the method of making toric contact lenses having a toric axis and ballast axis located on the anterior and posterior surfaces of a lens. Detectable features are formed on the anterior and posterior mold sections corresponding to the location of the toric axis and ballast axis, respectively. An axis alignment tool having detecting means thereon is used to set the mold sections to a known angular position. The desired axial offset is input into a computer which establishes the axial offset between the mold sections.

Toric axis alignment machine and method

A method for transferring a lens-shaped article from a first support to a centered position on a second support employs a transfer tool having a slideable plunger and plunger sleeve that cooperates with the first and second support to ensure that the article is oriented in a desired manner when transferred.

A microscope is provided which is simply, accurately and inexpensively constructed from substantially all extruded parts. The modular construction of the microscope greatly reduces the costs of the instrument without sacrificing accuracy. The modularity further provides for a microscope which is readily adaptable to serve several distinct and separate functions.

Multi-use microscope having modular construction of extruded parts

A support member for a precision optical instrument includes an integral bearing guide member for providing relatively friction-free movement to a movable member. The integral member 15 is pivoted with respect to the movable member to adjust the amount of play between the support member and the movable member.
