Presbyopia is a fact of life. When patients get to their late 30s or early 40s, they begin to lose the ability to focus comfortably at near. Eventually, intermediate vision [...]

Inflammation is the body's way of responding to a physical or chemical insult. When a stimulus is presented, the immune system releases histamine and other chemical mediators to address the [...]

Many times I am asked why anyone would bother with bifocal or multifocal contact lenses. Many associate these lenses with longer chair time, higher product costs and a more difficult [...]

The article highlights several cases that illustrate the relatively straight-forward approach for fitting GP lenses to postsurgical eyes. One case suggests that resultant lenses provide 20/20 vision Oculus Dexter (OD), Oculus Sinister (OS), and Oculus Uterque (OU) at distance and near, with optimal fit and comfort. Another case reveals that intraocular lens (IOL) improves comfort and vision, with visual acuity of 20/25 OD and 20/20 OS at distance and near.

The article discusses the basics in bifocal or multifocal lens fitting. There are two basic design philosophies for bifocal contact lenses namely simultaneous image designs and alternating image designs. In the first type, the retina is presented with images from multiple distances at all times while in the second type there is a dedicated area for distance and for near. There are a number of methods to achieve the goal of making patients see comfortably and the best one is the total bifocal fit.

The article presents the author's view on the latest technology and the old technology in eye care. It mentions that the measurement of visual acuity with the help of Snellen wall chart had some drawbacks and they were removed by the use of projected charts. It includes that contact lenses have evolved and development of polymethylmethacrylate plastic lead to the formation of smaller lenses.

In this article, the author focuses on the lens-wear safety compliance of contact lens patients. He tells that noncompliance is a part of life in general in every rule or every regulation. He says that there are three parts in the contact lenses noncompliance which includes contact lens wear schedule, lens care, and contact lens replacement schedule. He believes that educating the patients can lead to improve compliance.

The article presents the author's insights on the importance of empirical fitting of gas permeable (GP) Multifocal Lenses. He states that designs of GP Multifocal lenses are easy to fit, thereby making diagnostic fitting unnecessary and mentions several guidelines in choosing the proper design such as good refraction and keratometric readings and the position of lower lid relative to lower limbus. He cites that he is confident that the lenses recommended through such fitting are 75% effective.

In this article, the author discusses the reasons why a rigid gas permeable (GP) multifocal contact lenses is the considered the best, particularly for patients with corneal astigmatism. Among the advantages of GP lens are the possibility of having several designs like bitoric, back toric and front toric designs and can be used for a bigger group of physiologic variables. It cites the importance of pupil size when deciding to use multifocal contact lenses.

In this article the author contends that diagnostic fitting is more appropriate approach for contact lens prescribing compared to empirical fitting. He notes the benefits of diagnostic fitting such as it allows patients to experience the feel of the contact lens on their eye. He believes that diagnostic fitting is the better approach for lens prescribing because it offers precise information during evaluation visit by knowing how the lens will perform on the eye and how good the vision will be.
