The Perry-Kolberg Titanium Motility/Support System is intended to provide a direct mechanical coupling of an ocular prosthesis to an orbital implant (eye sphere implant) in order to enhance motility of the prosthesis over that of a prosthesis used without a direct coupling to the implant. It also reduces the weight of the ocular prosthesis on the lower eyelid. It may be placed in a secondary operation that occurs after the ocular implant has become vascularized, approximately three to six months after implant placement. Alternatively, it may be placed during the initial implantation procedure before closing the Tenon's capsule and the conjunctiva.
The Perry-Kolberg (PK) Titanium Motility/Support System consists of the PK Titanium Threaded Sleeve, the PK Titanium Flat Peg for Sleeve, the PK Titanium Locking Socket Peg for Sleeve, the PK Titanium Motility Ball Peg for Sleeve, the PK Titanium Threaded Sleeve Wrench and a scries of PK Titanium Needle Drill Handles. The latter two devices are Class I, exempt devices, and are included in this submission only for reference and to explain the use of the PK Titanium Motility/Support System. The Threaded Sleeve is an excernally threaded cylinder with an internal drilled hole designed to receive a peg. It is placed in the Bioeye® Hydroxyapatite Implant with the use of the PK Titanium Threaded Sleeve Wrench after a hole is prepared in the implant by drilling with a series of hypodermic needles of gradually increasing size, from 21-gauge to 14 gauge. The needles are held with the PK Titanium Needle Drill Handle.
After the Threaded Slecve is placed in the implant, any of the PK Motility Pegs can be inserted. The PK Titanium Flat Peg for Sleeve can be used as a temporary device to maintain the integrity of the drilling hole or can, in some cases, be used to directly attach to the ocular prosthesis. The PK Titanium Locking Socket Peg for Sleeve is designed to aid in retention of a prosthesis even in extreme gazes by locking into the ocular prosthesis and avoiding the loss of engagement of the peg and the motility hole. It is manufactured with a shaft length that is adjustable in one millimeter increments by the ocularist, to mect each patient's individual requirements. A non-adjustable ball and socket peg, the PK Titanium Motility Ball Peg for Sleeve, is also included in the system.
The provided text is a 510(k) summary for the Perry-Kolberg Titanium Motility/Support System. It discusses the device's substantial equivalence to previously marketed devices and does not describe a study involving specific acceptance criteria, device performance metrics, sample sizes, expert involvement, or any form of AI for performance evaluation.
Therefore, I cannot provide the requested information from the given text. This document is a regulatory submission for market clearance based on substantial equivalence, not a clinical or performance study report.

Perry-Kolberg Titanium Motility/Support System 510(k) SUMMARY
DEVICE DESCRIPTION
Design Characteristics
The Perry-Kolberg (PK) Titanium Motility/Support System consists of the PK Titanium Threaded Sleeve, the PK Titanium Flat Peg for Sleeve, the PK Titanium Locking Socket Peg for Sleeve, the PK Titanium Motility Ball Peg for Sleeve, the PK Titanium Threaded Sleeve Wrench and a scries of PK Titanium Needle Drill Handles. The latter two devices are Class I, exempt devices, and are included in this submission only for reference and to explain the use of the PK Titanium Motility/Support System. The Threaded Sleeve is an excernally threaded cylinder with an internal drilled hole designed to receive a peg. It is placed in the Bioeye® Hydroxyapatite Implant with the use of the PK Titanium Threaded Sleeve Wrench after a hole is prepared in the implant by drilling with a series of hypodermic needles of gradually increasing size, from 21-gauge to 14 gauge. The needles are held with the PK Titanium Needle Drill Handle.
After the Threaded Slecve is placed in the implant, any of the PK Motility Pegs can be inserted. The PK Titanium Flat Peg for Sleeve can be used as a temporary device to maintain the integrity of the drilling hole or can, in some cases, be used to directly attach to the ocular prosthesis. The PK Titanium Locking Socket Peg for Sleeve is designed to aid in retention of a prosthesis even in extreme gazes by locking into the ocular prosthesis and avoiding the loss of engagement of the peg and the motility hole. It is manufactured with a shaft length that is adjustable in one millimeter increments by the ocularist, to mect each patient's individual requirements. A non-adjustable ball and socket peg, the PK Titanium Motility Ball Peg for Sleeve, is also included in the system.
Material Composition
All of the components of the PK Titanium Motility/Support System are made from titaniumaluminum-vanadium conforming to ASTM Specification F136. Titanium and titaniumaluminum-vanadium alloy are well-recognized for their biocompatibility and are used as negative controls in many biocompatibility tests.
EQUIVALENCE TO MARKETED PRODUCT
IOI submits the following information to demonstrate that the Perry-Kolberg Titanium Motility/Support System shares indications and design principles with the following predicate devices, each of which has been determined by FDA to be substantially equivalent to pre-amendment devices: MEDPOR Ocular Screw and Accessories (K971583). MEDPOR Ocular Peg System and Accessories (K960859), MEDPOR Ocular Screw and Accessories (K954939).
{3}------------------------------------------------
Intended Use
The indications for use of the PK Titanium Motility/Support System are not new indications in that they are the same as or are included in those for the predicate devices. All are intended to provide a direct mechanical coupling of an ocular prosthesis to an orbital implant (eye sphere implant) in order to enhance motility of the prosthesis over that of a prosthesis used without a direct coupling to the implant.
Page
Design and Materials
The design and functional characteristics of the PK Titanium Motility/Support System and the predicate devices are similar. All are simple threaded cylindrical devices that are designed to be inserted into an orbital implant and to engage an ocular prosthesis by means of a head or peg. This provides the ocular prosthesis with improved motility over that of a prosthesis that is not coupled to the orbital implant. The MEDPOR predicate devices are available in both high density polyethylene (HDPE) and in titanium alloy, the material of the subject device. The subject device and the predicate devices are accompanied by instruments for threading or inserting the screw or peg into the ocular prosthesis. The subject device and the MEDPOR Ocular Screw are designed for either primary or delayed placement in the orbital implant.
The lay distinctions between the devices are that the PK Titanium Motility/Support System and the MEDPOR Ocular Peg System (K960859) are both two-piece systems consisting of an outer threaded sleeve that is inserted into the ocular implant and a peg that is inserted into the outer sleeve, while the MEDPOR Ocular Screw (K971583, K954939) is a one-piece device that must be inserted into the ocular implant with the head protruding exactly as it will be used by the ocularist. No adjustment is possible, without further surgical treatment, after the screw is placed.
The PK Titanium Motility/Support System combines the principles of operation of the twopiece MEDPOR Ocular Peg System with the titanium alloy composition of the MEDPOR Ocular Screw. The degree of protrusion of the PK Titanium Motility/Support System can be adjusted by use of the PK Titanium Locking Socket Peg for Sleeve, which is notched to allow for the removal of the appropriate length of its shaft before insertion. Pegs of the MEDPOR Ocular Screw can be adjusted for length by cutting off the necessary portion of the shaft.
