“…Previous studies have focused on different lens materials and determined their effects after various forms of refractive surgery on the visual and ocular parameters ( Table 6). [9,11,[18][19][20][21] PureVision (Balafilcon A) was compared with other BCLs in several studies, but not with PureVision 2, therefore the confound of lens material and design has not been minimized. Difference in performance of Acuvue Advance (Galyfilcon A) and PureVision (Balafilcon A) has been attributed to the mechanical characteristics such as higher modulus (1.1 vs. 0.43MPa), center thickness (0.09 vs. 0.07mm) of PureVision (Balafilcon A) lenses.…”

“…[3,4] There are a wide variety of silicone hydrogels commercially available. [5] The key features considered to select the optimum BCL include its oxygen permeability, water content, wetting agents, diameter, base curve and modulus. [6] Several studies have investigated the effect of different materials on the epithelial healing, visual outcomes and subjective assessment of pain and discomfort after corneal refractive surgery; [7][8][9][10][11] however, they could not determine which specific parameters influence the contact lens's performance or its role during the healing process.…”

To compare the efficiency and safety of two bandage contact lenses after photorefractive keratectomy (PRK). Methods: In this double-blind study, 45 patients (90 eyes) received PRK in both eyes and wore bandage contact lenses (BCLs), PureVision (Bausch & Lomb, Rochester, NY, USA) in one eye and PureVision2 (Bausch & Lomb, Rochester, NY, USA) in the other eye, randomly assigned. The medication regimen after surgery was the same for both eyes. The epithelial defect's size, conjunctival hyperemia and lens centration were graded objectively using slit-lamp biomicroscopy on days 1, 3 and 5 after surgery. Also ocular symptoms of discomfort including tearing, photophobia, foreign body sensation and visual fluctuations were assessed subjectively at each visit. Results: The mean epithelial defect size on the first day after operation was similar in eyes fitted with PureVision (30.08 ± 5.30 mm²) and PureVision2 (30.25 ± 5.72 mm 2) lenses. (p=0.79) Contact lens deposits and bulbar hyperaemia on days 1 and 3 after PRK were similar between the two eyes, but were significantly greater on day 5 for PureVision2 lenses. (p= 0.02; p= 0.04 respectively) There was no difference in contact lens decentration, and discomfort symptoms including pain, tearing, foreign body sensation, photophobia and visual fluctuations between the eyes fitted with PureVision and PureVision2. (p>0.05) Conclusions: PureVision and PureVision2 contact lenses are equivalent as bandage lenses in the important aspects corneal re-epithelialization and subjective comfort., although PureVision2 led to a higher incidence of contact lens deposits and conjunctival hyperemia early post-PRK.

“…Soft contact lenses have become widely adopted for use in alleviating discomfort and improving epithelial healing associated with ocular surgical procedures, such as refractive surgery [ 158 ]. Clinical studies have investigated the use of bandage contact lenses in the treatment of dry eye and other ocular conditions associated with aqueous deficiency.…”

Dysfunctional tear syndrome (DTS) is a common and complex condition affecting the ocular surface. The health and normal functioning of the ocular surface is dependent on a stable and sufficient tear film. Clinician awareness of conditions affecting the ocular surface has increased in recent years because of expanded research and the publication of diagnosis and treatment guidelines pertaining to disorders resulting in DTS, including the Delphi panel treatment recommendations for DTS (2006), the International Dry Eye Workshop (DEWS) (2007), the Meibomian Gland Dysfunction (MGD) Workshop (2011), and the updated Preferred Practice Pattern guidelines from the American Academy of Ophthalmology pertaining to dry eye and blepharitis (2013). Since the publication of the existing guidelines, new diagnostic techniques and treatment options that provide an opportunity for better management of patients have become available. Clinicians are now able to access a wealth of information that can help them obtain a differential diagnosis and treatment approach for patients presenting with DTS. This review provides a practical and directed approach to the diagnosis and treatment of patients with DTS, emphasizing treatment that is tailored to the specific disease subtype as well as the severity of the condition.

“…Therapeutic contact lens, also known as “bandage lens,” is designed to protect and facilitate the healing of a sick eye. Serving as a blanket for the cornea, bandage lens retains its moisture, promotes epithelialization [ 9 ], blocks small wound leaks, relieves suture irritation [ 10 ], and smoothens wound margin irregularities. A modified bandage lens can also act as a drug delivery system [ 11 , 12 ].…”

Purpose To explore whether bandage lenses could be a safe and effective substitute for eye patch in the postoperative care for cataract surgery patients in terms of infection prevention, ocular impacts, and patient satisfaction. Methods Patients who underwent cataract surgery were randomly divided into the eye patch group (Group A) and the bandage lens group (Group B). Bacterial culture samples were collected perioperatively from different sites. Evaluations of anterior segment condition and patient satisfaction were conducted on the first day of postoperative follow-up. Results The positive rate of bacterial cultures in Group A was higher than that in Group B, but the difference was not statistically significant. Group B had significantly longer tear breakup time, higher tear meniscus height, and slightly better patient satisfaction than Group A. Conclusion Bandage lenses can be used as a safe and effective substitute for eye patch in the postoperative care for cataract surgery patients. The Clinical Study registration number is ChiCTR-IOC-17012167.
