Surveys device classification, labeling requirements, and professional prescribing standards for contact lenses. Grounds clinical practice in compliance obligations.

Lesson 2 • Ocular Anatomy for Lens Fitting

Covers corneal topography, limbal anatomy, and conjunctival zones relevant to lens placement. Provides the anatomical baseline for all fitting decisions in this course.

Lesson 3 • Tear Film Physiology and Stability

Examines the three-layer tear model, evaporation rates, and osmolarity. Connects tear film health directly to lens comfort and wearing time.

Lesson 4 • Lens Parameter Terminology

Defines base curve, diameter, power, and sagittal depth in clinical terms. Ensures precise communication during fitting and ordering.

Lesson 1 • Slit-Lamp Biomicroscopy for Lens Assessment

Covers illumination techniques, magnification selection, and grading scales for lens-related findings. Slit-lamp skills underpin all clinical evaluation throughout the course.

Lesson 2 • Anterior Segment OCT Imaging

Introduces OCT cross-sectional imaging for corneal thickness, epithelial mapping, and lens vault assessment. Connects imaging findings to fitting adjustments.

Lesson 3 • Aberrometry and Wavefront Analysis

Explains Hartmann-Shack wavefront sensing and higher-order aberration maps. Aberrometry data informs custom lens designs for optimized visual quality.

Lesson 4 • Keratometry Principles and Technique

Covers manual and automated keratometry, mire alignment, and reading interpretation. Accurate K-readings form the starting point for all lens fitting calculations.

Lesson 1 • Empirical and Trial Lens Selection

Compares empirical ordering from measurements versus trial lens fitting protocols. Establishes decision criteria for choosing the appropriate starting approach.

Lesson 2 • Soft Lens Troubleshooting

Addresses common complaints including dryness, blur, and discomfort with systematic differential diagnosis. Troubleshooting skills consolidate all prior soft lens knowledge.

Lesson 3 • Toric Soft Lens Fitting

Covers cylinder axis marking, stabilization mechanisms, and rotation compensation calculations. Toric fitting builds on spherical skills with added rotational complexity.

Lesson 4 • Multifocal Soft Lens Fitting

Introduces simultaneous-vision and alternating designs, add power selection, and binocular balance. Presbyopic fitting requires integrating refraction with lens optics.

Lesson 1 • Fluorescein Pattern Interpretation

Teaches systematic reading of apical clearance, bearing, and edge lift using sodium fluorescein. Pattern interpretation is the primary diagnostic tool in RGP fitting.

Lesson 2 • RGP Adaptation and Patient Education

Covers adaptation schedules, lens care systems, and managing patient expectations for RGP wear. Patient adherence to adaptation protocols determines long-term success.

Lesson 3 • Fitting RGP Lenses on Irregular Corneas

Applies RGP fitting principles to keratoconus, post-surgical, and post-trauma corneas. Irregular cornea fitting demands advanced pattern reading and design customization.

Lesson 4 • RGP Parameter Modification

Explains how to adjust base curve, diameter, and peripheral curves to correct fit problems. Systematic modification skills reduce chair time and lens remakes.

Lesson 1 • Scleral Lens for Ocular Surface Disease

Applies scleral lens fitting to severe dry eye, Stevens-Johnson syndrome, and limbal stem cell deficiency. Therapeutic fitting requires integrating medical history with lens design.

Lesson 2 • Advanced Scleral Lens Troubleshooting

Addresses fogging, midday vision decline, lens awareness, and conjunctival prolapse systematically. Advanced troubleshooting integrates all scleral fitting knowledge into clinical problem-solving.

Lesson 3 • Vault and Landing Zone Optimization

Covers OCT-guided vault adjustment and slit-lamp landing zone grading for blanching and impingement. Optimization ensures corneal clearance and limbal health throughout wear.

Lesson 4 • Initial Scleral Lens Selection

Teaches diagnostic set selection, insertion technique, and initial vault and landing assessment. Correct initial selection minimizes fitting steps and chair time.

Lesson 1 • Monitoring and Long-Term Management

Establishes follow-up schedules, topographic monitoring, and discontinuation criteria for ortho-k programs. Ongoing monitoring protects corneal health and sustains treatment outcomes.

Lesson 2 • Orthokeratology Principles and Mechanisms

Explains epithelial redistribution, corneal flattening, and peripheral defocus created by ortho-k lenses. Mechanistic understanding guides target selection and patient candidacy.

Lesson 3 • Patient Selection and Candidacy

Covers refractive, topographic, and lifestyle criteria for ortho-k candidacy in children and adults. Proper selection prevents treatment failure and manages expectations.

Lesson 4 • Ortho-K Lens Design and Fitting

Teaches reverse geometry lens zones, target power, and fluorescein bull's-eye pattern evaluation. Design and fitting skills determine treatment efficacy and corneal safety.

Lesson 1 • Corneal Hypoxia and Edema

Covers Sattler's veil, striae, folds, and neovascularization caused by chronic hypoxia. Recognizing hypoxic signs drives material and wearing schedule modifications.

Lesson 2 • Dry Eye and Lens Interaction

Differentiates contact lens-induced dry eye from primary dry eye disease and guides management. Accurate diagnosis prevents unnecessary lens discontinuation.

Lesson 3 • Mechanical and Toxic Complications

Addresses superior epithelial arcuate lesions, solution toxicity, and lens-induced papillary conjunctivitis. Mechanical and toxic etiologies require distinct management pathways.

Lesson 4 • Complication Grading and Documentation

Applies standardized grading scales and clinical photography for complication documentation. Consistent grading enables longitudinal monitoring and medicolegal protection.

Lesson 1 • Hybrid Lens Fitting

Teaches hybrid lens vault selection, skirt curve fitting, and troubleshooting for irregular corneas. Hybrid lenses combine RGP optics with soft lens comfort for challenging patients.

Lesson 2 • Prosthetic and Cosmetic Lens Applications

Addresses iris prosthetic lenses for disfigurement, aniridia, and photophobia management. Prosthetic fitting integrates cosmetic goals with functional vision and ocular health.

Lesson 3 • Custom Soft Lens Design

Covers parameter customization beyond stock ranges, including high powers, steep bases, and large diameters. Custom soft lenses extend soft lens benefits to patients who fail stock designs.

Lesson 4 • Pediatric and Special Population Fitting

Covers aphakic infant fitting, pediatric RGP protocols, and fitting patients with disabilities. Special populations require modified techniques and enhanced communication strategies.
