ABO Domain 3: Refractive and Cataract Surgery Welcome to your ABO Domain 3: Refractive and Cataract Surgery 1. ABO: Refractive and Cataract Surgery What is the primary risk associated with performing LASIK surgery on patients with keratoconus? A. Increased risk of developing dry eyes B. Potential for significant overcorrection C. Risk of exacerbating corneal thinning and progression of keratoconus D. Decreased contrast sensitivity post-operation None 2. ABO: Refractive and Cataract Surgery In cataract surgery, what is the purpose of performing capsulorhexis? A. To remove the natural lens of the eye B. To create a circular opening in the anterior capsule of the lens C. To insert the intraocular lens (IOL) D. To reduce postoperative astigmatism None 3. ABO: Refractive and Cataract Surgery Which intraocular lens (IOL) type is designed to correct presbyopia by providing multiple focal points? A. Monofocal IOL B. Toric IOL C. Multifocal IOL D. Phakic IOL None 4. ABO: Refractive and Cataract Surgery What is the primary benefit of using femtosecond laser technology in cataract surgery compared to traditional phacoemulsification? A. Shorter overall surgery time B. Elimination of the need for intraocular lenses C. Greater precision in capsulotomy and lens fragmentation D. Reduced cost of surgery None 5. ABO: Refractive and Cataract Surgery What is the significance of the term "effective lens position" (ELP) in the context of cataract surgery? A. The physical position of the IOL in the eye post-surgery B. The ideal placement of the incision site C. The predictive measurement for IOL power calculation D. The final refractive outcome post-surgery None 6. ABO: Refractive and Cataract Surgery Posterior capsular opacification (PCO) after cataract surgery is primarily treated using which of the following methods? A. Application of topical corticosteroids B. YAG laser capsulotomy C. Additional phacoemulsification D. Suture adjustment in the surgical wound None 7. ABO: Refractive and Cataract Surgery Which of the following best describes the risk of inducing corneal ectasia in refractive surgery? A. Higher with PRK than with LASIK due to the surface ablation technique B. Higher with LASIK due to the creation of a corneal flap C. Unrelated to the type of refractive surgery performed D. Only associated with the use of outdated excimer laser technology None 8. ABO: Refractive and Cataract Surgery In the context of IOL power calculation for cataract surgery, what does the term "axial length" refer to? A. The diameter of the cornea B. The curvature of the anterior corneal surface C. The length of the eye from the anterior cornea to the retina D. The thickness of the lens to be implanted None 9. ABO: Refractive and Cataract Surgery What is the main advantage of "topography-guided" LASIK over conventional LASIK? A. Shorter recovery time B. Lower risk of infection C. Ability to customize the ablation pattern based on individual corneal curvature D. Elimination of the need for an eye tracker during surgery None 10. ABO: Refractive and Cataract Surgery Why is corneal pachymetry important in the preoperative evaluation for refractive surgery? A. To determine the corneal thickness and assess the risk of postoperative infection B. To measure intraocular pressure accurately C. To assess the suitability of the cornea for the creation of a flap or removal of tissue D. To evaluate the tear film stability None 1 out of 10 Time is Up! Time's up
