At Manhattan Vision Associates, we strive to meet all of your eye and vision care needs. Corrective lens evaluations and prescription management are provided by our optometrists at MVA. After a comprehensive eye and vision evaluation, the doctor will discuss the variety of contact lens options with you to select the type that best fits your vision needs and lifestyle. If you suffer from dry eye, allergies, or recurring eye infections, speak with our staff to determine whether contact lenses are right for you.
Prior to prescribing contact lenses, our doctors determine what level of vision correction you require. Refractive error (commonly known as nearsightedness, farsightedness, or astigmatism depending on the error) is evaluated by measuring how the eyes focus when a series of different lenses are placed in front of them. An optometrist may use either a phoropter or an automated instrument to take these measurements. To schedule an appointment for a vision evaluation with our optometrists, call (212) 688-4277 today.
After determining the level of refractive error, the optometrist works with you to determine whether contact lenses or glasses are best for your lifestyle. If you suffer from certain conditions, such as dry eye or allergies, glasses may be the most comfortable corrective solution. Contact lenses are available in either soft or rigid gas permeable form. Contact lenses need to be changed daily, weekly, bi-weekly, or monthly, depending on what type of lens you select. Specialized contact lenses, such as bifocal contact lenses, are also available for patients with special eye conditions. Call us at (212) 688-4277 if you are interested in learning if contact lenses are a good fit for you.
Advances in contact lens technology have created great options for cosmetic and prosthetic lenses. Custom contact lenses can be created to camouflage any color variation or irregularity and produce a natural eye color. Cosmetic lenses are also available to transform your eye color. Call us at (212) 688-4277 and speak to our knowledgeable staff if you are interested in modifying or changing your eye color with contact lenses.
Many ocular conditions can make it difficult to wear standard contacts. Some of the most typical reasons include:
- Corneal scarring
- Dry eye syndrome
- Pellucid Marginal Degeneration
- Post-LASIK, or other refractive procedure
- High Astigmatism
Rigid Gas Permeable Lenses
- Rigid gas permeable (RGP) contact lenses allow a high quantity of oxygen to reach your eye. RGP lenses are a preferred choice for many patients with high astigmatism, high visual demands, or irregular corneas.
Scleral Lenses and Keratoconus
- Keratoconus refers to a condition in which the cornea is thinner than normal and bulges outward into a cone shape. Standard soft contacts do not sit well on this shape, and we often fit our keratoconus patients with scleral lenses – rigid gas permeable contacts with an extra-wide diameter. Scleral specialty contact lenses vault over the cornea and rest of the white portion of your eye. They thereby replace the irregular corneal surface with a smoothly rounded surface, allowing for crisp vision.
- Hybrid contact lenses have a hard RGP center and an outer ring composed of soft contact lens materials. They bring the best of both worlds to wearers – with the comfort of a soft lens and the crisp vision of a hard lens. Our eye doctors fit hybrid lenses on normal and irregular corneas, and they are also available as multifocals.
Orthokeratology (Ortho-k) Lenses
- Ortho-k describes the process of temporarily reshaping the cornea to resolve refractive error, such as myopia. Ortho-k lenses are worn nightly while sleeping and removed upon awakening. The result is clear daytime vision, without wearing any eyeglasses or contact lenses during the day.
- Along with the convenience of ortho-k lenses, studies have shown that these specialty contact lenses provide myopia control; they slow or halt the progression of myopia by up to 50%.
Myopia (or nearsightedness) is very common. The prevalence has almost doubled worldwide within the past two decades, and the age of onset is decreasing at an alarming rate.
What causes myopia?
The formation and progression of myopia are multifactorial. It is suggested that genetic and environmental influences have intricate interrelation.
- Ethnicity: the ratio of myopic prevalence between European Caucasians and Asians ranges from 1:3 to 1:8
- Parental myopia: not only increases the incidence of myopia but also plays a significant role in the progression of myopia. The progression of myopia is much faster if both parents are myopic, especially if both parents are highly myopic.
- Duration of reading/near tasks: near work is an independent cause of myopia
- Near-work distance: reading or performing near tasks closer than 30 cm is associated with significant myopia, especially when one or both parents are myopic
- Lack of outdoor activities: children of any ethnicity are more prone to become more myopic when less time is spent outdoors
Myopia Control Options
- Low-dose atropine drops: Applied once a day, atropine treatment is continued as long as myopia progression continues
- Orthokeratology (Ortho-k) Lenses: Contact lenses are worn overnight, and the gentle pressure exerted on the cornea temporarily molds the cornea so that during the day no glasses or contact lens prescription is needed
- Multifocal Soft Contact Lenses: Distance Center Multifocal Soft Contact Lenses are worn precisely the same as regular soft contact lenses and have been shown in several studies to slow down the progression of myopia
