1In Manual Small-Incision Cataract Surgery (MSICS) performed according to the surgical standards of the Instituto Cubano de Oftalmología 'Ramón Pando Ferrer', what is the primary structural feature of the scleral tunnel that ensures a self-sealing wound without mandatory sutures?
A.A three-plane stepped incision extending 1.5 to 2.0 mm into clear cornea with a funnel or chevron internal architecture
B.A single-plane radial incision placed exactly at the anatomical limbus
C.A full-thickness scleral groove positioned 5.0 mm posterior to the limbus without corneal dissection
D.A purely clear-corneal bevel incision measuring 6.5 mm in width
Explanation: According to Cuban MSICS protocols refined at the Instituto Cubano de Oftalmología 'Ramón Pando Ferrer' (based on Blumenthal and Hennig techniques), self-sealing wound architecture relies on a triplanar scleral tunnel. The tunnel begins with a partial-thickness scleral groove (about 50% depth) 1.5 to 2.0 mm behind the limbus, tunnels forward 1.0 to 1.5 mm into clear cornea, and enters the anterior chamber with a sharp keratome, creating an internal corneal flap that is pressed closed by intraocular pressure.
2During the Blumenthal technique of MSICS for a mature brunescent cataract, how is the nucleus hydro-expressed through the internal wound opening into the anterior chamber maintainer (ACM) environment?
A.By applying high-vacuum aspiration using an automated irrigation-aspiration handpiece inside the capsular bag
B.By applying direct posterior depression on the scleral tunnel floor with a glide or cyclodialysis spatula while continuous anterior chamber hydrostatic pressure from the ACM pushes the nucleus out
C.By placing a cryoprobe directly onto the anterior cortex through an unexpanded pupil
D.By performing manual nucleofracture into quadrants strictly within the vitreous cavity
Explanation: The Blumenthal technique utilizes an anterior chamber maintainer (ACM) placed via a 20G side-port that delivers continuous balanced fluid infusion. When the surgeon depresses the posterior lip (floor) of the scleral tunnel using a lens glide or spatula, a pressure gradient is established; the continuous positive hydrostatic pressure behind the prolapsed nucleus pushes it smoothly out through the tunnel without entering intraocular instruments beneath the nucleus.
3In phacoemulsification, what is the fundamental fluidic difference between a peristaltic pump system and a Venturi pump system regarding vacuum generation?
A.A peristaltic pump relies on compressed gas flow across a constriction, whereas a Venturi pump relies on flexible rotating rollers
B.A peristaltic pump generates instantaneous vacuum throughout the fluid line, whereas a Venturi pump requires complete mechanical occlusion of the phaco tip
C.A peristaltic pump generates vacuum only when the aspiration port is physically occluded by lens material, whereas a Venturi pump can generate preset vacuum instantly without occlusion
D.A peristaltic pump cannot achieve vacuum levels higher than 50 mmHg, whereas a Venturi pump operates only at atmospheric pressure
Explanation: A peristaltic (flow-based) pump moves fluid by compressing tubing with rotating rollers; vacuum is generated only when fluid flow is restricted or occluded by lens material at the phaco tip. In contrast, a Venturi (vacuum-based) pump operates via the Venturi effect using gas flow over an orifice, creating preset vacuum immediately in the cassette regardless of whether the tip is occluded, which provides high followability.
4During quadrant removal in phacoemulsification, the surgeon observes sudden deepening of the anterior chamber, asymmetric pupil dilation, and loss of fragment followability. What is the immediate, imperative first surgical action?
A.Inject 1 mL of intracameral pilocarpine 2% directly into the wound while continuing ultrasound power
B.Immediately pull the phaco handpiece out of the eye and increase the infusion bottle height to maximum
C.Switch to maximum aspiration vacuum to quickly evacuate the remaining nuclear fragments before vitreous presents
D.Maintain the phaco tip in position inside the eye, stop aspiration, lower the infusion bottle, inject a dispersive ophthalmic viscoelastic device (OVD) through the paracentesis, and only then withdraw the tip
Explanation: Sudden AC deepening, pupil snap, and loss of followability are hallmark signs of posterior capsule rupture. The surgeon must freeze the foot pedal in position 1 (or 0) to avoid aspirating vitreous, keep the tip in the eye to prevent chamber collapse, lower infusion pressure to avoid hydrating the vitreous, inject a dispersive OVD through the side-port to tamponade the vitreous face and support remaining fragments, and only then withdraw the phaco tip under viscoelastic cover.
5When performing an anterior vitrectomy following posterior capsule rupture, which intraoperative pharmacological adjunct is standard at the Instituto Cubano de Oftalmología 'Ramón Pando Ferrer' to visualize transparent vitreous strands in the anterior chamber?
A.Preservative-free triamcinolone acetonide suspension diluted 1:1 or 1:4 with balanced salt solution
B.Trypan blue 0.06% ophthalmic solution
C.Indocyanine green (ICG) 0.5% solution
D.Fluorescein sodium 10% intravenous solution
Explanation: Triamcinolone acetonide crystals physically adhere to vitreous collagen fibrils, rendering transparent vitreous strands opaque and starkly white. This allows the surgeon to verify complete clearance of vitreous from the anterior chamber, paracentesis sites, and main incision during bimanual anterior vitrectomy. Trypan blue stains the anterior capsule, not vitreous.
6A 72-year-old patient undergoing biometry before cataract surgery has an axial length of 26.2 mm and average keratometry of 42.5 D. Which intraocular lens (IOL) calculation formula is most accurate and widely recommended for eyes with high axial myopia?
A.Hoffer Q with original axial length
B.Barrett Universal II (or modified Wang-Koch axial length adjustment with SRK/T)
C.SRK I linear formula
D.Holladay 1 without axial length modification
Explanation: In long myopic eyes (axial length > 25.0 mm), older vergence formulas systematically overestimate IOL power, leading to post-cataract hyperopic refractive surprises. Modern fourth-generation and new-generation formulas such as the Barrett Universal II, or SRK/T with Wang-Koch axial length adjustment, accurately calculate the effective lens position and IOL power in high axial myopia.
7When a posterior capsule tear occurs with an intact, stable anterior capsular rim (continuous curvilinear capsulorrhexis), a three-piece IOL is chosen for ciliary sulcus placement instead of in-the-bag implantation. What rule-of-thumb power adjustment is standard relative to the calculated in-the-bag power?
A.Keep the exact same power without modification regardless of IOL position
B.Add 1.5 to 2.0 Diopters to the in-the-bag calculation
C.Subtract 0.5 to 1.0 Diopter from the in-the-bag calculation (for standard powers)
D.Subtract 3.5 to 4.0 Diopters from the in-the-bag calculation
Explanation: Because the ciliary sulcus lies anatomically anterior to the capsular bag, placing an IOL in the sulcus moves the optic closer to the cornea. This anterior shift increases the effective optical power of the lens. To maintain the intended postoperative refraction, the surgeon must subtract 0.5 D (for IOL powers between 17.5 and 28.0 D) or 1.0 D (for powers > 28.0 D).
8When implanting an open-loop flexible anterior chamber intraocular lens (ACIOL) as a secondary procedure in aphakia, how is the correct overall lens diameter calculated, and which additional surgical step is mandatory?
A.Axial length divided by 2, combined with anterior vitrectomy only
B.Vertical white-to-white minus 1.0 mm, combined with posterior capsulotomy
C.Exact pupil diameter in photopic conditions, without peripheral iridectomy
D.Horizontal corneal diameter (white-to-white) plus 1.0 mm, combined with a surgical peripheral iridectomy
Explanation: Correct sizing of an open-loop ACIOL requires measuring the horizontal white-to-white (WTW) corneal diameter using calipers and adding 1.0 mm. Sizing too small leads to rotation and endothelial touch; sizing too large causes chronic angle tenderness, cyclitis, and iris chafing. A surgical peripheral iridectomy (PI) is mandatory to prevent pupillary block glaucoma.
9On postoperative day 1 following uncomplicated phacoemulsification, a patient presents with diffuse limbus-to-limbus corneal edema, marked anterior chamber fibrinous reaction with a 1 mm hypopyon, and visual acuity of counting fingers. There is no pain, and B-scan ultrasonography reveals a clear vitreous cavity without vitritis. What is the most likely diagnosis?
A.Toxic Anterior Segment Syndrome (TASS)
B.Acute bacterial endophthalmitis
C.Delayed-onset Propionibacterium acnes endophthalmitis
D.Fungal endophthalmitis
Explanation: Toxic Anterior Segment Syndrome (TASS) is a sterile inflammatory reaction to non-infectious toxic substances introduced into the anterior segment (e.g., detergent residues, enzyme cleaners, endotoxins on autoclaved instruments, preserved intraocular drugs). Hallmarks are onset within 12 to 24 hours, painless or mildly uncomfortable presentation, limbus-to-limbus corneal endothelial edema, prominent fibrin/hypopyon, and a completely clear vitreous on B-scan. Endophthalmitis typically presents 3-7 days postoperatively with severe throbbing pain and vitritis.
10According to official surgical protocols at the Instituto Cubano de Oftalmología 'Ramón Pando Ferrer' and international evidence, what is the most effective evidence-based pharmacological prophylaxis against acute post-cataract endophthalmitis administered at the conclusion of surgery?
A.Subconjunctival injection of gentamicin and dexamethasone
B.Intracameral injection of cefuroxime (1.0 mg in 0.1 mL) or moxifloxacin (0.5 mg in 0.1 mL)
C.Topical chloramphenicol eye drops instilled every 10 minutes for 1 hour
D.Oral ciprofloxacin 750 mg given as a single postoperative dose
Explanation: Intracameral antibiotic prophylaxis at the conclusion of surgery—specifically cefuroxime (1.0 mg/0.1 mL) or moxifloxacin (500 mcg/0.1 mL)—has demonstrated a 5- to 6-fold reduction in acute postoperative endophthalmitis in landmark clinical trials and is the standard practice guideline at the Instituto Cubano de Oftalmología 'Ramón Pando Ferrer'. Preoperative 5% povidone-iodine in the conjunctival sac is the mandatory complementary antiseptic measure.
