Addressing post-surgical vision loss, which may occur after procedures such as LASIK or RK, necessitates a tailored approach grounded in the specific circumstances and needs of each patient. Several complications and symptoms may arise post-surgery, posing challenges to both the treating physician and the patient, which include, but are not limited to:
Despite the absence of an established cure for several of these complications, advancements in specialized lenses provide promising avenues for improving both the visual function and comfort levels of post-surgical patients. Among the diverse options of specialized lenses, including various soft lens and gas permeable lens designs, two lens designs stand out for their efficacy in addressing the challenges faced by most post-refractive surgical patients: Synergeyes Post-Surgical Lens and Post-Surgical Scleral Lenses.
Synergeyes Post-Surgical Lenses are classified as “hybrid” lenses, as they integrate a highly oxygen-permeable central area with a soft peripheral section. This unique construction is tailored to comfortably fit over irregular corneas without irritating the compromised corneal tissue. The soft peripheral portion of the lens promotes exceptional comfort while ensuring a stable fit. The Synergeyes lens is characterized by a highly resistant juncture between the soft and rigid components, preventing tearing or damage. Additionally, its oxygen permeability is hundreds of times higher than previous models, ensuring healthier corneas.
Scleral lenses, on the other hand, are large gas permeable lenses designed to vault over the compromised cornea and rest on the sclera, the white portion of the eye. These lenses create a protective barrier filled with a special liquid between the lens and the cornea, which aids in corneal healing and hydration, while providing optimal vision and comfort. The protective layer established by scleral lenses shields the healing cornea from external irritants, such as dust, allergens, or air conditioning, and the blinking action of the eyelids, facilitating the healing process.
The decision on the most suitable lens technology cannot be predetermined and often, both lens types are fitted during the initial session to save time and reduce the number of follow-up visits. The choice may depend on specific patient circumstances, such as the presence of a weakened Lasik flap or incomplete healing, where a scleral lens might be the optimal choice.
These advanced lens designs offer superior vision by presenting a rigid material along the line of vision, effectively replacing the cornea as an optical surface. In contrast, while soft lenses offer comfort, they conform to the shape of the irregular cornea, thus, they cannot provide the sharp, clear vision that rigid lenses do. Additionally, soft lenses may exacerbate dryness and hinder tissue regeneration, as they rest directly on the distressed cornea. In essence, these advanced lenses offer post-surgical patients a path towards improved vision and a higher quality of life.
Post-surgical vision loss refers to a decrease in visual acuity following an eye surgery like LASIK or RK. It can result from several complications including irregular or misshapen corneas, persistent wounds, higher order aberrations, decentered optic zones, corneal ectasia, extreme dry eye syndrome, ocular discomfort, vitreous floaters, reduced contrast sensitivity, degraded night vision, overcorrection of the pre-surgical refractive error, and others.
The complications of post-surgical vision loss can significantly affect a patient’s quality of life, leading to psychological and emotional repercussions. Challenges can include blurred vision, persistent discomfort, headaches, and difficulties distinguishing objects from their backgrounds, among others.
Specialized lenses like Synergeyes Post-Surgical Lenses and Post-Surgical Scleral Lenses can significantly improve both the visual function and comfort levels of post-surgical patients. These lenses are designed to fit over irregular corneas without causing irritation, aiding in the healing process, and providing optimal vision and comfort.

By improving vision and comfort levels, these advanced lenses can significantly enhance the quality of life for post-surgical patients. They aid in corneal healing, protect the eye from external irritants, and provide sharper vision, helping patients overcome the complications of post-surgical vision loss.
