Introduction

Monofocal lenses are a kind of lens used in cataract surgery. And Cataract surgery is a procedure that entails the removal of the opaque natural lens of the eye. The insertion of an artificial lens to improve vision, Unlike multifocal lenses. Although Monofocal lenses can provide clear vision at multiple distances, they can only correct for a single distance.

Monofocal lenses may require glasses to see clearly at other distances. Monofocal lenses are covered by insurance and can provide significant improvement in vision for those with cataracts. Doctors can help choose the best lens for individual needs.

Cataract surgery restores clear vision in people with cataracts. IOL replaces natural lenses to improve vision.

There are several types of IOLs available, including monofocal lenses, which are a popular choice among cataract patients. Monofocal lenses provide clear vision at a single distance, either near, intermediate or far. In this article, we will explore everything you need along with knowing about all the monofocal lenses available in cataract surgery.

Types of Monofocal Lenses

01.

Fixed-focus Monofocal Lenses:

Fixed-focus monofocal lenses are the most commonly used type of IOLs in cataract surgery. These lenses provide clear vision at a single distance. Furthermore usually distance vision, and require patients to wear glasses for reading or close work. Fixed-focus monofocal lenses are available in various materials, also including acrylic, silicone, and hydrophilic acrylic.

02.

Monovision Monofocal Lenses:

Monovision Monofocal Lenses correct Presbyopia. These lenses are put in to provide clear distance vision in one eye and also clear near vision in the other. Monovision Monofocal Lenses reduce the need such as glasses for post-cataract surgery.

03.

Aspheric Monofocal Lenses:

An Aspheric monofocal lens is shown to provide for better image quality as opposed to traditional spherical lenses. Lens design mimics cornea to improve contrast sensitivity. Aspheric monofocal lenses are ideal for patients who have higher-order aberrations (Specific distortions with the eye's structure).

04.

Toric Monofocal Lenses:

Toric monofocal lens corrects astigmatism. These lenses contain different powers in different meridians and can also help correct astigmatism and improve vision. Toric monofocal lenses are available in various materials (including acrylic and silicone) and are ideal for patients with significant astigmatism.

Monofocal lenses are a common type of intraocular lens (IOL) used in cataract surgery. While the lens provides distance vision, and patients require glasses for close work. Monofocal lenses are a safe and effective option for cataract surgery. However, they do have advantages and disadvantages to consider.

Advantages of Monofocal Lenses:

1.

Safety and Efficacy:

Monofocal lenses are old for decades and also are a deep-rooted option for cataract surgery. They have a high rate of success and also a low complication rate.

2.

Affordable:

Monofocal lenses are a cost-effective option for some patients.

3.

Effortless to Implant:

Monofocal lenses are almost easy to implant with minimal recovery time.

4.

Availability:

Monofocal lenses are available in different materials to meet individual needs.

Advantages of Monofocal Lenses

1. Safety and Efficacy:

Monofocal lenses have been old for decades and are a deep-rooted option for cataract surgery. They have a high rate of success and also a low complication rate.

3. Effortless to Implant:

These are almost easy to implant with minimal recovery time.

2. Affordable:

Affordable IOLs are a surely good option for some patients.

4. Availability:

Unifocal lenses can be customized to meet individual needs.

Disadvantages of Monofocal Lenses

1. Limited Field of Vision:

Monofocal lenses provide clear vision at a single distance. This could later turn out to be inconvenient for a few patients.

3. Monovision Could Be Challenging:

Monovision is a method where one eye is corrected for distance vision while the other is corrected for near vision. And also reducing the need for glasses can take time to adjust.

2. Does Not Cure Presbyopia:

Monofocal lenses do not correct presbyopia, while glasses are required for near vision.

4. Astigmatism Cannot Be Corrected:

Monofocal lenses cannot correct Astigmatism (a condition where the cornea or lens of the eye is not perfectly round). Patients with Astigmatism might need a toric IOL or additional refractive surgery to put right their vision.

To conclude, Monofocal lenses are a safe and efficacious option for cataract surgery. However, they do have a few drawbacks to consider. While they can be a cost-effective option and are easy to implant, they cannot correct Presbyopia or Astigmatism and have a limited field of vision. Patients should consider discussing their individual needs and preferences with their eye doctor to ascertain whether a monofocal lens is their best option.

Some of the best-known mono-focal Iols are:

1) Johnson & Johnson’s IOLS:

a. Tecnis 1 Single Piece ZCB00 is a 6.0 mm biconvex hydrophobic acrylic lens with an anterior aspheric surface. This is one of My personal Favourite as everything about this monofocal lens is about safety, comfort, and ease of doing surgery. These lenses are Hydrophobic in Nature and can be put within a 2.2mm Incision. The front surface results in a negative Spherical Aberration (SA) of 0.27 m and frosted continuous 360 posterior square edge prevents Dysphotopsia and Posterior Capsular Opacification (PCO) available Ranges+5.0 to +34.0 (0.50 Increments) Package price at Vijaya Nethralaya is 50,000Rs (approx USD 608) 49825.6 rs by Expert Surgeon.

b. Sensar 1 Single Piece AAB00: These lenses are spherical lenses. The performance of these lenses is excellent during the day. The Doctor implanting the IOL can utilize the optical properties of this lens and enhance vision by utilizing the optical properties of the cornea. And also these lenses reduce chromatic aberration and produce long-term performance, the SENSAR IOL can help you give patients reliable quality vision. These Lenses are Hydrophobic in nature and can be put within 2.2mm opening. The package price at Vijaya Nethralaya Bangalore is Rs 40,000(approx $486 USD) by a senior surgeon.

c. Sensar 3 Piece AR40E/M/e: These lenses have the same optics as Sensar 1 piece, but the lens is shown up of two materials and this significantly decreases the cost of manufacturing. The Sensar 3 piece is also available in a much wider range than in other Lenses manufactured by Johnson and Johnson. Sensar 3-piece lenses are the safest alternative backup lenses used by surgeons worldwide. Sensar 3-Piece is available from -10.0 to +30.0 Dioptres. This lens can be put in a 2.8 mm Incision. The Cost of Implanting Sensar 3 Piece at Vijaya Nethralaya Superspeciality eye Hospital by an expert Phaco surgeon is Rs 35,000 (Approx USD 426).

d. Tecnis Eyhance IOL ICB00: The TECNIS Eyhance IOL, is a one-piece, lens with an overall diameter of 13.0 mm and an optic diameter of 6.0 mm. It incorporates a spherical posterior surface and a modified aspheric anterior surface that is shown to provide distance vision and a dysphotopsia profile comparable to a standard aspheric monofocal IOL. The lens has a depth of focus, which provides improved intermediate vision compared to a standard aspheric monofocal IOL. Because of this feature, this lens has become one of my personal favorites. The lens also compensates for corneal spherical aberration, similar to the TECNIS monofocal IOL. Powers: +5.0 D to 34.0 D in 0.5 diopter increments. The Cost of Implanting Tecnis Eyhance at Vijaya Nethralaya is Rs 60,000 (Approx USD 730) by an experienced surgeon.

e. Tecnis Toric IOL ZCT 100-800: This lens works on the Tecnis 1 platform. These Lenses help to correct Astigmatism. You can get this lens implanted based on the scans done and your requirement. (Kindly note that Toric Iol Implantation is just One of the ways to correct Astigmatism). If you have astigmatism then its wiser to undergo this implant. The cost of undergoing surgery with this implant is RS 65000 (Approx $791 USD) by an experienced surgeon at Vijaya Nethralaya.

Tecnis Eyhance Toric: DIU150-600: These lenses work on the Tecnis Eyhance platform. These Lenses surely correct Astigmatism. You could get this lens implanted based on the scans done and your requirement. (Kindly note that Toric Iol Implantation is Just One of the ways to correct Astigmatism). If you have astigmatism then it’s wiser to undergo this implant. The cost of undergoing surgery with this implant is RS 75000 (Approx $912 USD) by an experienced surgeon at Vijaya Nethralaya.
