disposable contact lenses

  1. 1. 1
  2. 2.  Convenience Health Quality Value 2
  3. 3. Consumers indicate that a"healthier lens" is the most important need 3
  4. 4. In their own words, consumers described"healthier" …"will not cause infection""better for you, better for your eyes""comfortable, lubricated, safe""optimal perfection, clean and pure""worry free, infection free""healthier body, vision, lifestyle""less strain, less maintenance, less infection""fewer side effects, wont cause problems" 4
  5. 5.  Contact Lens that is better than spectacles Contact lens that is free from all complications Contact lens that can be worn in the eye for longer duration without removal 5
  6. 6. Conventional Contact Lenses Parameter Changes Physiologic compromise leading to tear film disruption and red eye reaction Contact Lens deposits Patient compliance Contamination with Microorganisms 6
  7. 7. Challenges to successful practice Deposits/Films Solution related hypersensitivity Contact lens induced papillary conjunctivitis Old, dirty and contaminated case Compliance 7
  8. 8.  Irritation / reduced comfort• Reduced visual acuity• Shorten wearing time (CL intolerance)• Increased potential for infection / inflammation 8
  9. 9. What are the ways to eliminate theseobstacles to successful contact lens wear? 9
  10. 10. Replace the lenses as often as possible 10
  11. 11. Disposable Contact Lenses“Designed to be thrown away after one use and not to be laundered or refilled” (Concise Oxford Dictionary) 11
  12. 12. Frequent Replacement Program (FRP)/ Planned Replacement Program (PRP) FRP/PRP Lenses“Intended to be worn &disinfected, on a daily wear basis andreplaced between 1 month and 3months”However some lenses are nowapproved for extended wear &Continuous Wear basis”. 12
  13. 13. Disposables and FRP lenses Objectives  Deposit free lens wear  Optimal wetting properties  Optimal Ocular health  Safe wear without many complicationsTo minimize, if not to eliminate, the need for the softcontact lenses to be handled and disinfected 13
  14. 14. Why should one switch to ? Disposable Contact Lenses? 1 2 3 For Better For For GreaterSuperior Hygiene and ConvenienceComfort Healthy Eyes 14
  15. 15. What are some of the additionalBenefits of Disposable Contact Lenses ?  Crisp Vision  Trouble Free Lens wear  Spare pair availability at all times  Better Value for Money 15
  16. 16. Disposable & FRP lenses Disadvantages  Cost  Compliance  Handling  Complications 16
  17. 17. What are the Benefits of Disposable Contact Lenses to Practitioners?  Reduced drop out rate  Fewer unscheduled visits  Healthy eyes, healthy practice  Increased profitability 17
  18. 18. Disposable Contact Lenses – Available Options 18
  19. 19. Disposable/PRP Lens Options• Based on Modality/ Replacement – Traditional/conventional and Disposable CL• Based on Wearing Time – Daily, Extended, and Continuous wear• Based on Lens material charge & Water Content – Ionic/Non-Ionic, Low/High Water• Correction indicated – Spherical, Toric, Presbyopic, Cosmetic 19
  20. 20. Disposable/PRP Lens Options• Based on Modality/ Replacement – Traditional/conventional and Disposable CL• Based on Wearing Time – Daily, Extended, and Continuous wear• Based on Lens material charge & Water Content – Ionic/Non-Ionic, Low/High Water• Correction indicated – Spherical, Toric, Presbyopic, Cosmetic 20
  21. 21. Classification based on Modality of CL wear Traditional YearlySoft Contact Lenses Daily (Disp) Disposable/ Bi-weekly Planned Replacement Monthly Quarterly 21
  22. 22. Disposable/PRP Lens Options• Based on Modality/ Replacement – Traditional/conventional and Disposable CL• Based on Wearing Time – Daily, Extended, and Continuous wear• Based on Lens material charge & Water Content – Ionic/Non-Ionic, Low/High Water• Correction indicated – Spherical, Toric, Presbyopic, Cosmetic 22
  23. 23. Classification based on Wear time Daily Wear: - Wear during wake hours; Requires daily removal & care. Extended Wear - Wear up to 7 days/ 6 nights, (Flexible Wear): without daily removal & care*. Continuous Wear: - Wear up to 30 days/ 29 nights, without daily removal & care*.*Silicone Hydrogels 23
  24. 24. Disposable/PRP Lens Options• Based on Modality/ Replacement – Traditional/conventional and Disposable CL• Based on Wearing Time – Daily, Extended, and Continuous wear• Based on Ionic charge & Water Content – Ionic/Non-Ionic, Low/High Water• Correction indicated – Spherical, Toric, Presbyopic, Cosmetic 24
  25. 25. Disposable/PRP Lens Options• Based on Modality/ Replacement – Traditional/conventional and Disposable CL• Based on Wearing Time – Daily, Extended, and Continuous wear• Based on Ionic charge & Water Content – Ionic/Non-Ionic, Low/High Water• Correction indicated – Spherical, Toric, Presbyopic, Cosmetic 26
  26. 26. FDA Classification of Lens Materials Group Water Content Charge I Low (< 50%) Non Ionic II High (> 50%) Non Ionic III Low Ionic IV High Ionic 27
  27. 27. Protein Uptake of Lens Materials ~ 26x more deposits than I, II, & III 28
  28. 28. Implications of Lens Material Classification Ionicity  Ionic materials have grater tendency to attract deposits compared to Non-ionic materials Water Content  Deposition: LWC deposits less than HWC lenses  Handling: HWC lenses are more flexible than LWC lenses  Oxygen flow: HWC transmit more oxygen than LWC lenses  Dehydration: HWC has greater dehydration potential than LWC 29
  29. 29. Disposable Contact Lenses – Patient Selection 30
  30. 30. Ideal Candidate for Disposable Lenses• Conventional lens wearers• Frequent protein deposit build up in CLs• Former CL wearer (*ask reason for drop-out)• Active lifestyle• Living in environmentally polluted areas• Ideal for those who seek convenience• Business travelers/ part time wearers/ young professionals• Patients with solution sensitivity• Patients who want to wear CLs for extended periods 31
  31. 31. Identifying a suitable PRP lens for your patientCounsel your patient on disposable modalityDetermine wear time: DW/ FW/ EW/ CW scheduleDetermine replacement scheduleHow to choose a suitable PRP?Thickness: For new patients - lens handling is important, chooseslightly thicker lensIonicity: Choose between ionic & non-ionic materials, based onpatient’s depositing responseWater content: Choose between HW & LW based on patient’sneeds 32
  32. 32. Identifying a suitable PRP lens for your patient Suggest silicone hydrogels, for patients that complain of end of the day dryness & discomfort with CLs (eg: Software professionals, & those working in AC environments) Advice to use lubricating eye drops when required For glare-free, crisp vision even at night, choose CLs that correct spherical aberrations (Eg: PureVision from B&L) Select appropriate vision correction i.e. spherical CL vs. toric CL Affordability 33
  33. 33. Fitting Disposable & FRP lensesFitting is similar to other SCL fittingFitting procedure much simpler with disposables, becauseof Unifit base curves (usually 8.6mm or 8.5mm)Similar patient managementReinforce compliance with replacement & wear scheduleEducate on cleaning procedures, avoid neglecting anypart of the procedure 34
  34. 34. SummaryFor Healthy Eyes - Choose Disposable/Frequentreplacement Lenses  Disposable lenses - a fast growing segment  First choice for new wearers, traditional wearers  Better choice for healthier CL wear  Refit choice for patients with complaints of poor handling, lens tearing & lens dryness 35
  35. 35. SummaryFor Healthy Eyes - Choose Disposable/Frequentreplacement Lenses Set a New Standard in Contact Lens Customer Care Enhance Consumer Satisfaction Promote Consumer Retention Reduce consumer Drop out 36
  36. 36. Happy & Satisfied Patients !! 37
