Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Comorbid Conditions

Factors Influencing Duration

Factors influencing the length of disability may include type and extent of procedure used, underlying conditions, severity of the condition, any complications associated with the procedure, and progression of the disease.

Medical Codes

ICD-9-CM:
12.1 - Iridotomy and Simple Iridectomy
12.11 - Iridotomy with Transfixion
12.12 - Iridotomy, Other; Corectomy; Discission of Iris; Iridotomy NOS
12.13 - Excision of Prolapsed Iris
12.14 - Iridectomy, Other; Basal, Peripheral, Total

Complications

Risks of complications for iridotomy are low, but some individuals may experience increased intraocular pressure immediately after surgery. Usually, the high IOP resolves within a few weeks. Rarely, individuals will develop cataracts as a result of laser surgery. Other complications include inflammation (iritis), abnormal growth of vessels (neovascularization), bleeding (hyphema), or infection.

A primary complication of iridectomy is failure of the incision to close properly. Other possible complications common to most eye surgeries include bleeding (hyphema), inflammation, infection of the iris (iritis), abnormal vessel growth (neovascularization), loss of too much fluid causing flattening of the eye, worsening of cataracts, swelling of the clear, outer layer of the eye (cornea), and permanent worsening of underlying glaucoma. These complications can result in permanent vision loss.

With both types of procedures, individuals who have had previous eye surgery have a higher risk of failure.
